San Francisco's 49-man roster of 53 people has more or less changed, forming a half-new team.

First of all, in the offensive group, the quarterback list, led by Lu Ke, Colin Kaepernick as the first bench, and Scott Tolcin as the second bench.

On the running back list, Kendall Hunter is on the injury list, Marcus Lynch and Frank-Gore are leading the way, and this year's second-round pick La Micheal-James and undrafted rookie Jule Hampton managed to stay on the list.

Among them, Gower was a three-round pick selected by the San Francisco 49ers in 2005, and is considered a veteran of the team, and was selected for the Pro Bowl twice in 2006 and 2009, missed most of the season last year due to injury, and then entered the sparring team list, and did not officially return to the team until this offseason to compete for the post.

The near end of the roster is led by Vernon Davis and Logan Newman, and undrafted rookie Garrett-Celek also managed to make the final list.

The wide receiver roster, Kyle Williams joins Michael Crabtree and Teddy Jean after returning from injury, plus this year's first-round rookie A-J. Jenkins (A-J-Jenkins), so the team has a full four wide receivers, but that's not all. The team's most important offseason poaching this year came from wide receivers.

Randy-Moss.

He was drafted by the Minnesota Vikings with the 21st overall pick in the first round in 1998. He was selected for the Pro Bowl six times, entered the All-American First Team four times, was the 1998 Offensive Rookie of the Year, and the five-time Receiving Touchdown King of the Year.

He has played for four teams, including the Minnesota Vikings, Oakland Raiders, New England Patriots, and Tennessee Titans.

In fact, in the Patriots' all-win season in 2007, he was in the middle of the line, with 98 catches and 1,493 yards, breaking the Patriots' all-time record for yards received in a single season. And that season, when the Patriots lost the most important game above the Super Bowl, Moss missed his first championship ring.

In 2010, after joining the Tennessee Titans, Moss's form declined very rapidly, his performance was not satisfactory, and after the end of the season, he unfortunately suffered layoffs; In 2011, Moss announced his retirement, ending his thirteen-year career; But in early March this year, Moss announced his official comeback via social media, and he hopes to find a strong team to play on his spare time.

Everyone knows that Moss wants to make a Super Bowl impact.

It was once said that perhaps Jerry-Rice is the greatest wide receiver of all time in the NFL, but Randy Moss is undoubtedly the most talented wide receiver. If Moss had been willing to give half the effort of an average player, he wouldn't have played in the Super Bowl only once in his thirteen-year career.

Since his college days, Moss's ability to create controversy has been no less than his talent for receiving touchdowns, and after he turns 30, he should be gradually maturing, but his speed and ability are declining, and his temper is growing. Except for Bill Bilicek of the Patriots, no one has been able to control Moss.

In the 2010 season, Moss returned to his parent team, the Minnesota Vikings, before leaving for the Tennessee Titans, but just four months later, he upset the entire team and repeatedly confronted the head coach, only to be swept away in embarrassment, and soon after, he signed with the Tennessee Titans.

Now, Moss is the third-all-time NFL record holder for receiving yards and second-most touchdowns all-time, and his greatness is unquestionable; But the question is, he's thirty-five years old, and after a full year of retirement, will he still be able to adapt to the intensity of the league? Especially the young cornerguards now, all of them are vigorous and fierce, and after losing their physical talents, how much energy can Moss dedicate?

All of this, this puts a big question mark on Moss's comeback.

Eventually, the San Francisco 49ers signed Randy Moss to a one-year contract. The head-on encounter between the fiery young coach Jim Hubble and the unruly veteran Randy Moss, and whether Lu Ke, a mere second-year quarterback, can tame the arrogant lone wolf have become one of the biggest variables in the team's offensive team.

In the offensive forward lineup, Jonathan Goodwin plays as the center, Mike Ruppati and Joe Stanley serve as protectors on the left blind side, and Anthony Davis and Alex Boone become protectors on the right.

Stanley switched from the right side to the left side, teaming up with Rupatti to protect Lu Ke's blind side; Boone was the player who caught the duck on the shelf in the federation final, and he didn't perform well at the time, but after the offseason, he managed to become the main starter, teaming up with Davis to protect Lu Ke's right side.

Incidentally, there are three other bench rotations on the offensive front, including this year's five-round pick Joe Looney.

And DeMarcus Dobbs, the undrafted rookie near end who has always insisted on fighting, suffered an injury unexpectedly and reluctantly entered the injury list, and his chances of playing this season are very slim.

On the whole, the changes in the offensive group are still focused on the changes and adjustments of the offensive front, looking forward to providing Lu Ke with a more solid and reliable pocket; In other positions, on the basis of last season, they have made up for the gaps and made small improvements, hoping to continue their good form.

This is also a benefit for young players. With rookie players as the main lineup, in the previous seasons, the personnel changes will not be too drastic, and the competitiveness will be relatively stable - of course, the biggest instability comes from the young people's own performance, which is a double-edged sword.

Comparatively, the defensive group is a bit older. But the San Francisco 49ers don't have a top superstar on their roster, and Patrick Willis, the central pillar of the team, signed a contract extension in 2010 and has nothing to worry about, which has allowed the team to continue last season's main defensive lineup.

In the offseason, the team mainly signed a number of substitute rotation players, increasing the depth of the bench in the defensive group; More changes have been made to the second-tier defence, with some new faces in the line-up for the corner-backs and back-backs, as there have been some changes to the starting line-up due to injuries and form.

But the noteworthy changes were not. The familiar names and faces have all been retained. There was only one point, and he accidentally bumped into Lu Ke's undrafted rookie defensive end Tony Gerald Eddie during the voluntary training camp, and he also stayed and made the final 53-man squad.

Interestingly, San Francisco 49ers have a total of seven undrafted rookies on the final roster, which is the highest percentage in the league.

But why? The media didn't ask, and Trent Balk didn't say.

From the offensive group to the defensive group, if you add the three core players of the special service group, the San Francisco 49ers basically continue the personnel of the 2011 season, purely on paper, they are still the most competitive team in the league, and if they can maintain the form of last season, they will also be the favorite team in the Super Bowl.

It's no wonder that when Peyton Manning was invited to join, Trent Balk repeatedly stressed that they are a team capable of winning championships, and all that is needed now is a top-level commander to lead the team in the right direction.

But, that's just if.

Why?

Looking at the opening game of the 2012 season, that's the best answer.

On September 5, the first game of the new season was officially played at the Mets Stadium, with the defending champions of New York Giants playing at home to their rivals Dallas Cowboys.

The New York Giants, who had just fought back against the championship as a dark horse last season, fell off the line again and lost the game with a score of "17:24"; And the Dallas Cowboys, who didn't even make the playoffs last season, have successfully ushered in a good start to the season.

This is the NFL, all accidents can happen, and the strength is often between the two; There are countless factors that determine the direction of the game and the championship, and no one can take it lightly, and at the same time, every team has the possibility of winning the championship. Whether it is a mule or a horse, you can only know when you come out to slip around.

San Francisco 49 is no exception.

Last season, the San Francisco 49ers were the second-seeded players in the National League, with a brilliant record; Naturally, this season, the San Francisco 49ers' schedule will also be more difficult.

Throughout the regular season, in addition to the civil war in the Western Division of the National League, within the league, the San Francisco 49ers will also play against the four traditional powerhouses in the North Division of the National League, and then against the New York Giants, the champion of the Eastern Division of the National League, and the New Orleans Saints, the champion of the Southern Division of the National League; Outside of the league, the San Francisco 49ers will play the American League East this year.

Putting aside the New York Giants and New Orleans Saints, two powerhouses that have faced each other in the playoffs, a look at the teams in the American League East and National League North can give you an idea of the difficulty of this season's schedule.

Midland Eastside, New England Patriots, New York Jets, Miami Dolphins, Buffalo Bills. It is foreseeable that the much-anticipated Lu Ke vs. Brady will be staged soon.

League of Nations North Side, Green Bay Packers, Detroit Lions, Minnesota Vikings, Chicago Bears. This time, it was the turn of the "Lu Ke VS Rogers" showdown.

If last season, the San Francisco 49ers played against teams that were generally not strong, but they unexpectedly broke out with strong immediacy and created difficulties for the schedule; Then this season, the San Francisco 49ers will face the bombardment of traditional strong teams, and the difficulty of the schedule has increased by more than one notch compared to last year.

Therefore, the speculation and rehearsal of strength on paper is "just if".

Under such a difficult schedule, the season prospects of the San Francisco 49ers are really difficult to give people more expectations and hopes.

For example, in the first week of the regular season:

The San Francisco 49ers are heading north to Wisconsin to take on the Green Bay Packers on the road.
