I don't think Bowe will be dropped this soon in most leagues just based on name recognition alone. He'd have to really stink it up for a few weeks for all but the most distressed/desperate owners to feel comfortable dropping him.
Shorts will have the, er, shorter leash but I also doubt he'll get dropped in many leagues.
Guys that will hit the wire this week are ones like Sudfeld, DHB, etc. Guys who were suspect to begin with and didn't show much in week 1. Owners short of patience or roster space due to injuries will drop them.
