i think the elite #1's have that breakaway speed - moss, steve smith, even TO. colston is very good, but he lacks that speed. he has shown that he can be very productive. that's what i meant when i said he's a great #2, but maybe not a GREAT #1. another downfield threat that can take the double team away from him is missing (henderson is not the answer).
maybe that's what the saints are thinking - that shockey will demand the attention of the safeties, because linebackers can't cover him. so then linebackers will have to guard bush. and it'll be harder to double colston. i see where they're going, but i wouldn't give more than a 2nd rounder and a role player, if that much.
