I would keep these 32 players ahead of him.
QB (6): Rodgers, Newton, Brady, Brees, Stafford, Vick
RB (17): Rice, McCoy, Foster, Mathews, Forte, MJD, DMC, Peterson, Charles, Gore, FJax, SJax, Turner, Lynch, CJ1K, Murray, Wells
TE (2): Graham, Gronkowski
WR (7): Calvin, Fitz, AJG, AJ, Jennings, Welker, Roddy
After that it's a crapshoot of 6 WR
Nicks, Wallace, Cruz, Smith, Harvin, Jordy
So I think he's a fine keeper in most formats, but I would have no trouble dropping him if it increased my chances of getting Richardson or if I had better options.
