From the free rivals article on Quinton Washington:
" . . . Michigan's win over Wisconsin and the Michigan Stadium atmosphere also played a role in swaying him"
(Chris Balas, 2/3/09, http://michigan.rivals.com/content.asp?CID=908121). (I cited it so to avoid any ire due to some sort of infraction)
It would be interesting to see how many visitors from that weekend, or other more frenzied and inspiring weekends (e.g., bb win over Duke), later commit. I was at the wisconsin game, which has stuck with me as one of the best games I have been to. I know I was inspired - they could have recruited me to clean the port-a-potties after that.
