I did not see this on the board this week.
USA today had a big article on Mallett in the Thursday or Friday edition.
It detailed his life-long Arkansas fandom, how he used to park cars at the stadium as a kid to get free tickets, and how he (essentially) was forced elsewhere by the Mitch Mustain signing at Arkansas.
The article notes that with the Mustain transfer and coaching changes at both U of M and Arkansas the door opened for Mallett to transfer.
I don't have the link as I read it the "old fashioned way" but it would be a good reference for those who say RR ran him out of town......his heart was always at Arkansas regardless of where he was actually playing.
