I'd think the only chance of a smoking gun(and it'd be a bad one) would be some sort of evidence of messing with Olt's injury to delay his DL stint. Olt didn't start after he was injured, appearing only as a pinch hitter and defensive replacement. He'd then sit the entirety of the final necessary game, and be DLd just in time for Bryant to gain another year. I don't know what records are available in these hearings, nor do I know how well-documented a training staff/doctors' review would be. But other than a don't ask/don't tell policy as the date approached, I'd be surprised if somebody wasn't informed Olt would need a DL stint.
