Yes, there's much more to Christopher than what Silas wasn't able to unlock. He showed more in his first season than his second. I'd watch Jalen G and Christopher in that first season and think that there is not a 20-draft-spot difference between them.
Oh I definitely thought there was a 20-draft-spot difference between them. I THOUGHT JOSH CHRISTOPHER SHOULD HAVE GONE 20 SPOTS AHEAD OF JALEN GREEN! I think that would have put him at the -17th pick.
