I don’t remember hearing that, but I do remember hearing (pre-draft) that Rosen was not well liked by his teammates at UCLA. He reminds me of Jeff George, only he doesn’t have as strong of an arm, and he’s probably not quite at the epic level of D-bag George was.
Actually, now that I thought about it... the reason Ramczyk lasted until the end of round 1 was because there were questions about how much he wanted to play football.
