Homerism at it's finest. IMO, chemistry is the biggest reason Brady to Welker was such a lethal combo. Amendola is a nice talent, and maybe his measurables are better than Welker's, but to assume that there will be little to no drop off in this scenario is silly.
As a Dolphin fan, I'm much happier to see Amendola in NE and Welker gone. I also can't believe that Tom Brady re-did his contract in an effort to take less money so NE could remain competitive. For him to do that, and then see his favorite weapon leave because the Pats wanted to get him on the cheap is a huge smack in the face to Brady.
Add to that the fact that NE doesn't seem to draft as well as they did years ago gives me hope that maybe this dynasty is finally starting to tail off a bit.
