Gil Brandt was saying right after the draft that this deal isn't dead even with the drafting of Lattimore.
The more time that passes, the less likely I think it is to happen. If he isn't traded for by the start of camp, I wouldn't think it would happen. Unless, of course, we start watching corners drop like flies again. I'd much rather Butler than another BW Webb type signing off the street (not a knock on Webb at all - he came in here and did a damn good job for someone who was selling cars or something when the season started.) if it happens again so early in camp/the season.
