1. WR - Robby Anderson would be the other field stretching guy that we can play opposite TY while using Parris Campbell underneath in the slot to use his speed for YAC or a "healthy" Funchess (or big bodied TE / Wide out from draft) for contested catches in the slot.
2. Depth signing at Cornerback - Darqueze Dennard, CB, Bengals, coming off knee surgery, most likely the Bengals will release him. He has been playing solid for them. Byron Jones would also be one I would want us to look from Cowboys.
3. Shelby Harris, DT, Denver Broncos - very unsung hero, we will not be disappointed if we sign this guy. He disrupts, and he does not have quite the name recognition that Chris Jones of KC has.
4. Another DT I want us to look at is Damion Square of the Los Angeles Chargers, he is a good 1-gap DT that disrupts as well.
I think if the Pats retool with better WRs and obtain better OL support, he'll be back to his old self. Also, the Pats run game is averaging about 1 yard less per carry in recent games. All of this has led to some of his struggles.
