I would grab Burleson.....BTW....he plays for Sea and not Stl as you had mentioned!
He has the best capabilities and most say Branch won't do anything (they almost cut him)
S.Smith is great himself and is the clear #1 on the Giants but too many WR's on that team for my blood! Crayton is in the same situation as Smith (I just don't see him doing what he did in week 1 every week) and Clayton is a good choice as Balt is throwing a ton these days but he has no real good history.
I think if Burleson remains healthy then he should fair the best out of these 4 guys!
