This is kinda off the subject but without wasting everyone's time, I will try and be brief in my thoughts here.
I think Kliff Kingsbury looks at Rosen and sees a QB who doesn't fit his system. I think that since he was not the HC who drafted him, he has no allegiance to him and is probably more interested in getting the QB who can make his system work. Since that person would probably be a rookie and Rosen is only a 2nd year QB, what you would be looking at is a young QB on his roster who probably never gets developed and never really helps the team. This has nothing to do with talent, it has to do with the time it takes to develop a Rookie QB. It's just too hard to try and develop two at the same time. I think Rosen is a dead end for Kingsbury and vice versa. Kingsbury is really probably doing Rosen a favor by trading him. When Az brought in Kingsbury, management basically wasted that 1st round pick and it had nothing to do with any decision Kingsbury made. Rosen doesn't fit that type of Offense. It's not a lack of talent thing IMO. Az new that going in so it is what it is.
