We know next to nothing about all of them except Mangum.

I will only go so far as to say that I wouldn't play Mangum unless he is in much better shape and with a better mindset than last year.

OK, maybe one or 2 of you guys have a lot more info than the rest of us, but even the coaches are working on very limited info right now.  Will need all of summer workouts and fall camp.  And even then, they won't know who will be the best in-game performer.
