Temperament and individual character are a complex mix. It isn't a simple diagnosis, so what is a positive contributor with one person might work against another. To many elements to be able to quickly discern, imo. I don't care about Rosen's quirky personality. I worry about the concussions. You better build a strong oline. That's always important, but with a somewhat lean fella with a history of concussions and poor pocket awareness (at least, that's what Mayock says, I don't know,) you better emphasize protection. Anyway, I like Rosen, but he's not my first choice.
