Take this for what it's worth but I am keeping a close eye on the Wes Welker situation here in New England. With the Patriots getting Jake Ballard last year in an unconventional manner (and also pissed off the Giants) and then to IR him for this year.
I think Ballard will be the other TE in starting lineup opposite Gronk. With that moving Aaron Hernandez over to the slot receiver role. That may impact a lot of players but I think Ballard might be a solid contributor in that offense.
Of course, this all depends on Welker and what the offseason brings...he is a sleeper IMO...
