The book on Rosen has been known for a while, that is only one example of a longer list. That new Browns FO is filled with highly regarded draft evaluators. Even Jim Mora Jr, Rosen's college coach, made some offhanded remarks about Rosen needing to mature, and college coaches rarely if ever do that. I know that people from the area have also described Rosen as a "tennis player at heart" (tennis was his first passion, and he was a top ranked junior before he switched to football).
