Rosen is bad. No mobility, doesn't sense the pressure well, and he is still the same guy. Say what you want as far as Allen's numbers go, but you can see the progression with him and he is more athletic than Rosen would ever dream of being. This is more than just a "numbers" debate, the eye test tells all. Allen is also clutch where Rosen has done nothing. To try and compare the two is foolish at best, maybe dopey even.
