Tressel is a stand-up individual who made a mistake, and (seemingly) realizes it, and gave himself a harsher punishment than he had to. I have no comment on whether he should be fired or not, but I am entirely confidence in his decency as a human being.
Let me get this straight. The stand up guy Tressle found out in a e-mail last April before football season that some of his top players were trading merchandise for cash or Tats which is against NCAA rules. He then does nothing to report the misconduct to the NCAA or his own school.
When this all came out in December this stand up guy then acts that he's outraged even though he knew this was going on in April. He then makes a big deal that unless the players pledge that they won't go pro the next year then they won't play in the bowl game.
Then it's found out he knew back in April he makes a appology and Ohio State gives him 2 game suspension. Only after he knows that the NCAA is not going to reduce the players 5 game suspension that he decides he going to add three more games to his penalty. (Probably to stall the NCAA from giving something worse then his being really contrite.) OH, what a web we weave when you first try and deceive.
I have no dog in this hunt. but can't see how the NCAA can let him get away with what he did with only a five game suspension.
