Sleeper potential in ARI WR corps?

The Arizona Cardinals rolled the dice on Texas A&M wide receiver Ryan Swope in the sixth round, despite the fact that he has a history of concussions. That's a particularly big concern for Swope, because he is a slot receiver, who is sure to take plenty of big hits when trying to reel in passes across the middle of the field. Even more concerning is that teammate Larry Fitzgerald hinted Tuesday that Swope may still be dealing with concussion issues.
