Let's see...
This is nothing. Typical teenager street brawl that is actually overblown. You're making a mountain out of a mole hill. Plus, Simmons apologized to the woman & her family, and made up for it.
He continued that remake of himself by becoming a 4.0 academic college student, contributor to his community, awareness speaker at public schools, and an outstanding player/teammate to his college team.
Not much else one can ask for. He made 1 teenager mistake which he corrected and learned from. Sounds like someone who should be congratulated, not admonished.
I definitely wouldn't mind if the Cowboys picked him. Granted, I personally would not use anything higher than a 3rd round pick on him, but I would have no problem with his character if the Cowboys picked him up.
