Hey, like I said - kudos to Pollard (or whoever) at ISU who managed to get that deal signed in a way that clearly benefits them. Getting a last home gate from Iowa in 2012 in the last year of this deal was a stroke of genius, especially when they get to keep the whole thing in 2013 when the new deal goes into effect.
My guess is that as part of the negotiations to get the unfavorable contract terms out of the deal, Barta had to (or agreed to) have the deal expire after that home game in 2012.
