We can hire Tressel tomorrow, no problem. However, your assumption is that the Infractions Committee will merely look at the University of Tennessee's hiring of Tressel with a benevolent attitude. Keep in mind that that is the same committee (including Greg Sankey, COO of the SEC) that threw the book at Tressel two years ago, calling Tressel's behavior "very serious, and frankly, disappointing" (

The same committee that did no find reason to administer additional punishments in 2011 for football, but that was after significant self-imposed punishments (and several resignations in BB and FB). This does not mean that UT was or is squeaky clean and above the reproach of the NCAA; quite the contrary. Given our history, and more importantly Tressel's history, it is possible if not likely that the NCAA would add to Tressel's suspension. I would not be surprised for them to make him ineligible for a full year.
Even if the committee did not choose to impose additional penalties beyond his suspension (from the first fall practice until after the 5th game on 10/18), the university would still be subject to additional penalties if he or any member of his staff committed any other infractions, even secondary violations. Remember the new enforcement regulations add to the head coach's responsibilities and his culpability for the actions of his staff (

Tressel would be a good choice under different circumstances, but unfortunately the risk would probably be waaaay too great to justify hiring him until 2016.
