According to Scout.com, after visiting Wisconsin over the weekend, Penn State offensive line commit J.J. Denman (4*, all recruiting services) rescinded his PSU commitment and is now pledged to the Badgers.
Denman is a Pennsylvania kid (Fairless Hills, PA) and committed to Penn State back in May:
Let there be no doubt that Penn State got a gem in Denman. The 6'6" 310 offensive lineman is a four star prospect on Scout, Rivals, and Lions 24/7. Denman had his choice of offers from schools like Michigan, Notre Dame, Miami (FL), Michigan State, Northwestern, Pitt, Wisconsin and about 20 other schools.
However, it's hard to argue with the success Wisconsin has had with developing offensive linemen and getting them to the NFL. Here is Penn State current recruiting situation in the trenches, courtesy of Junny's weekly recruiting summaries (although position switches are almost always in play for the big guys).
