the maturity and off the field character flaws Kelly hinted at. That indeed can cost Kizer millions because even slipping 10 spots in the draft because some GM suddenly wonders if there is a hidden problem amounts to losing millions.
Ideally Kizer would get teams that don't draft him to go on the record about why after the fact and then he could have grounds to sue Kelly for slander.
GMs learn about character issues they can't uncover via interviews and film and the combine largely by interviewing the head coach of the prospect and then working outward from there. So, Kelly's comments are extremely damaging.
