He is a loud mouth, obnoxious radio talk show host in Pgh. I haven't listened to him in years, and I am not sure what station he is with at this time. He prefers talking about hockey (and soccer), but in Pgh sports talk radio you only survive if you talk Steelers 80% of the time. He likes to say controversial things, and has been fired from at least 1 radio station because of it. He also had a brief pro-wrestling background with TNT as an interviewer or announcer, which probably explain his radio talk show style. I would seriously doubt he has any Penn State or Munchak sources - it is likely he just picked this up from another station or blog.
