Legett wasn't invited. Don't know anything about him. WR is the least of the Cards' concerns right now, though improving depth (along with nearly other WR) should be in the back of the Cards' minds.
Great article. Steve Breaston is a pretty terrible WR. Bad hands, bad concentration, bad routes. He was a terrible WR in college that was a huge disappointment. Maybe he'll decide that he wants to play WR because he can get a better contract if he's at least adequate as a #3, but I'm not going to hold my breath.
If a player falls into the Cards' laps in the draft, they shouldn't pass on him. Otherwise, it's not a real concern.
