I've had a lot of conversations with various people about him and am surprised how mixed the opinions are. I'm even more shocked with the opinions of letting Welker walk and not reaching a deal is O.K. with some people, and how they don't even want to tag him. It's strange.
I find it interesting that Gronk and Hernandez's performances seem to have clouded the fact that if Welker's gone, their depth chart consists of Underwood, Edelman, Branch, Slater, and Ochocinco. They lose either one (and especially as we learned, Gronk) and the offense instantly becomes less effective if Welker's not here.
I understand the arguments after Moss left because it allowed them to stop heaving the ball down the field in hopes that he'd come down with it and getting back to distributing the ball better. However, Welker is more dynamic (or versatile - if you'd prefer that word) than Moss and he showed even more of that this season. Considering how thin they are at wideout, I'm just surprised there's so many people who are ready to let him walk. I love the thought of Wallace coming here as much as the next guy, but they need someone like him (or more realistically LLoyd or Wayne) to compliment Welker in this offense. I think losing Welker leaves them with a big void because they really need at least two decent receivers, which they just don't have right now. Branch is a #3 or #4 at best at this stage of his career, which as I've mentioned before is O.K. because that's what he should be. He's Troy Brown at this point, although he can't play defense
But I'm just trying to understand the thoughts of some of the people who are cool with letting Welker walk and would love to know who would like to see them keep him (whether it's franchising him, or an extension) vs people that want to see them move in another direction and why they feel that way.
After a bunch of post, I've gone back to respond to the OP.
To me you have to accept that Wes Welker is the focal point of the offense.
I understand Brady is the man, but what the style they play revolves around Welker, and the coverage they face also is dictated by Welker being the focal point.
So a logical question would be whether the offense with Welker as the focal point is good, or whether a change should be made to improve it.
In looking at this, first I think while the offense has undergone a tremendous amount of change, I think it is fair to look at the entire timeframe of 07-11 to assess it, because, ups and downs aside it has been reasonably consistent in where it ranks among NFL offenses. While this includes the great 2007 offense it also includes 16 Matt Cassel ganes.
Some numbers:
First the Patriots have a 64-16 record over these 5 years. Second best is 55-25
Points scored #1 with 2457 (30.7 a game) 174 ahead of #2.
Point differential #1 with 934, second place is 696
Passing Yards 2nd
Total Offense 2nd
Passing TDs 1st (tied)
Passing ints fewest
Total turnovers fewest
I think it is reasonable to assume that the Patriot offense, as constructed is effective.
To not retain Welker will have to result in a scheme change.
For my money, change for the sake of change when you are already excellent is foolhardy.
One final point. I hear so many comments about Welker not being a 'real' WR and how some slug could do what Welker does.
Wes Welker had the 19th most receiving yards in a single season in NFL history in 2012. IN HISTORY.
Yards are production regardless of how they are gained.
To put some perspective to this, Jerry Rice only had 2 seasons in his career with more receiving yards than Welkers 2012 and one was by a single yard.
Randy Moss exceeded it once.
The only active players with more recieving yards in any of their career seasons are Andre Johnson who surpassed it by 6 yards once, and tied it another, and Calvin Johnson who used a career day in week 17 to surpass Welker who led all season.
How people can think we just go out and get a guy to replace Welker when there are only 2 men in the league who ever had more receiving yards in any season of their career is mind boggling to me.
I guess people just want to reduce his career to dropping that pass in Indy.
