That's an interesting question. When you think about it this offense is constantly being reinvented. Pryor to the 2010 season the Pat were basically a 3 WR passing offense, attacking deep with Moss and underneath with Welker, with minimum contributions from the TE's and RB's. After 2010 the 2TE's offense appeared without the deep threat, but still a predominantly a passing attack. Then in 2013 the running attack appeared along with an outside the number threat, but still no true "deep threat" (whatever that means)
I don't want to belabor it, but I sincerely hope the Pats and Welker reach some accommodation that keeps him here for the next couple of years, and doesn't cripple their ability to maintain a prudent salary cap structure. However to think that this offense isn't capable of being productive without Wes Welker is ludicrous. In 2006, with the fewest offensive weapons in Brady's career (since 2002) the Pats were STILL the 11th most productive offense in the league.
Somehow I think, with Gronk, Hernandez, Llyodd and the most productive running attack we've had since Cory Dillon, (and this one might even be better because of its depth and versatility);the Pats offense wouldn't fall too far down the stats lists.
Personally the big question on Welker is not whether he's "worth" the money, but rather what is the long term effect tying up that kind of money will have on the rest of the team. Its a very delicate balance. EVERY big signing has to be weighed in that light.
It might not be his fault (due to injuries) but we can safely say that Logan Mankins hasn't been worth his contract the last 2 years. Injury potential IS a factor. I know Welker has been extraordinarily dependable the last 6 years, but Mankins was too. He hadn't missed a practice through 2010 in his career. Over the last 2 years there's hardly been a week when he hasn't been on the injury report. That's how fast things can change.
We all talk about how great the last 3 draft have been. That's the good news. The bad news is that very quickly those guys are going to be coming up to FA, and that has to be prepared for, and the resignings we do this off season, will directly effect the ones we make in years going forward.
OT - a question - I know we had some obscene amount of dead money on the books this season (IIRC over $20MM). Does anyone know approximately what that number will be next season?
