At least according to combine numbers, Coale isn't that much worse an athlete than Ogletree. Really, straight line speed is the only thing Ogletree has that Coale doesn't, and that's not to say that Coale is slow.

I think Ogletree's reputation as stupid has less to do with his skin color and more to do with his performance in last year's Commanders@Cowboys game, the one in which he claimed Romo called him "stupid."
Coale has a reputation as a gym rat. His dad is a trainer at VPI. Ogletree said after his brother's death that he has never taken football as his first priority.
I don't think anything that anyone's said in this thread is untrue, except maybe for the part that implies Coale is much less athletic than Ogletree.
