You're right about Childs. It looks as if he's their #2 RB. Against Washington (his first game as a Grizzly) he had 9 rushes for 39 yards (4.33 average).
His transfer was, to me, the most unexpected, surprising transfer I've ever seen. His senior year in HS he chose us over Kansas State, and on social media was 100% all Zips up to his eyeballs. I thought he'd be a team captain by the time he was a junior. Then he got to campus for summer training/fall camp, and transferred out before the season even began (IIRC). Totally weird. But following him on social media he really seems positive and level headed; not at all flaky; a future Mr. President type of young man. (Much like LePear Toles, if you're at all familiar with his social media presence.) Big red flag for the UA staff? I still don't know what to make of it, as he seems to be precisely the type of athlete/person the current staff is targeting, and there are other positive, mature, true student-athletes on the team who seem to be loving it (e.g., Snowden).
