No Univ PSA ads during NCAA's?

I don't recall seeing any University PSA's during the NCAA games last week. Have they ever done them? Is CBS able to dictate there will be none because it cuts into their ad revenue? Re: PSA's, it still is impossible to beat Michigan in Space, although I did like the jazzed up "Hail" a year ago. I also kinda liked USC's famous alumni PSA's. As much as I hate ND, I thought their "fighting Irish" PSA with the doctor fighting disease wasn't bad. Has James Earl Jones ever narrated a PSA for his alma mater? In a way, I'd like to have several PSA's around a theme that have very short clips of famous alums in that field, with Jones narrating all of them. James Earl Jones and Lucy Liu and Gilda Radner in one, Griese and Harbaugh and Brady in another, Harmon and Howard and Woodson in another, Fadell (iPod), Bloch (H&R Block), Page (Google), and Walgreen (Walgreens) in another, Dierdorf, Guisewaite, and Wallace in another. Regardless, I don't like the same lame cute, diverse student body PSA's with test tubes and the main diag and a lecture and a lab. Too many schools do this. Lastly, PSA's will be tainted for me for many years by Brian's pre-mocking of Appalachian State with "Hot, Hot, Hot." http://www.youtube.com/watch?v=pVENWl8uBeg. While I'm not superstitious (re: Liveblogs,) this mocking came back to bite us in the butt.
