Thanks for the help with mine!
Start Bowe, he always gets many looks in the end zone, plus is a great WR and is having a pretty easy matchup.
Start Sims-Walker, he has around 12 looks per game, that can't hurt anybody, specially against a pouring pass D as KC's
The toss up would be between Megatron and Gates, leave Crabtree out, Vernon Davis always scores the air TD's, Alex Smith is under center and Crabtree has had 13 points in 2 games which is really not impresive. I know he will be a good WR, but it just won't happen this season.
I would go with Megatron because he is the best player in Detroit, they are always looking for him, the only thing that scares me about him is that he hasn't had chemistry with Stafford who is not playing well, that would be the only reason I would start Gates over him, Gates would be more consistent, but if Megatron explodes, you could be missing 20+ points.
Hope it helps!
