I think it is a very good team, maybe because it looks so similar to mine. I'm in a 12-team, all TDs 6pts, 1-PPR league where TE's are optional and counted as WR and you can play 3WR-2RB or 4WR-1RB:
Welker/J. Graham/Torrey Smith/Meachum/Titus/A. Jeffery/D. Baldwin
I'm with the other posters, you have to handcuff Tate to Foster. Tate has proven he can produce similarly in the event of injury. Wells is an enigma and Williams is going to be brought along slowly. You'll be guessing who to start between the two every week. I'd dump Wells for Tate and keep Williams for the upside.
