I think that the Pats will be fine. Brady will put up Brady numbers like he always has. Amendola might not do exactly the same kind of things as Welker, but he'll put up a lot of production. My memory is somewhat faulty, but I don't recall Welker being an "All word receiver" until he got up here and had Brady throwing to him. If Amendola can make it through the season and not get injured, he'll put up good numbers. Edelman and Boyce have also looked good according to most reports I've seen.
It looks like Brady will have some receivers with size and speed this year. Dobson and Thompkins have been having a good camp so far, from what I have read. Can't wait to see how they do in preseason games.
I like the fact that Brady has new guys around him and think that he'll distribute the ball more. To me, this is a plus. Reasoning, I look at Detroit with Megatron putting up stupid stats, and noticed that Detroit sucked. Arizona also came to mind with Fritz putting up nice numbers, yet they have sucked as well. Spreading the ball out more means that we won't be slowed down as much by opponents trying to take certain targets away, or that injuries would be as harmful.
TE situation could be better, but Fells has looked pretty good as has Sudfeld. Won't compare to Gronk and Ahern, but will be fine especially if/when Gronk comes back healthy. Haven't read all that much about Hooooooom.
RB situation is all to the good. Pats were 7th in rushing last year with Ridley and Vereen. Have heard good stuff about Bolden, haven't heard too much positive about Blount.
That covers the skill positions. Good enough ?
