Can we really validate this? I mean, yeah - there are people who are rubbed the wrong way by him. But there's another side to this coin, the players on UCLA who completely vouched for Rosen as a player and a leader. Heck, even now - with all the rumors around a trade - Kliff Kingsbury has went out of his way to praise Rosen this off-season:
This could be to boost his trade value, it could be to repair a fractured relationship, or it could be genuine. We don't really know.
So I'm not sure if this talk of people not liking him is holdover from his UCLA days, magnified by this trade talk; I'm always the type to say "where there's smoke, there's fire," but I don't know if we're talking about a controlled burn or a forest fire in this case.
I'll put it like this - the Cardinals could very well select Murray and trade Rosen this Thursday. If they do, they are in line for an 0-16 season (because it's not like Murray is going to do any better with that Arizona offense) and somebody just got a top 10 QB for peanuts and will look incredibly smart in 2-3 years.
I just hope it's not the Patriots.
