I listened to Herbstreit on ESPN Radio today on Mike and Mike. He was on for ten minutes, mainly talking about the big games of the weekend (Texas/WVU, USC/Georgia, ND/Miami, LSU/Florida). He then briefly said his two upsets of the weekend are Northwestern over PSU and Purdue over Michigan. He said Purdue was the best team in the Big Ten this year, and are now his pick to go to the Rose Bowl.
rundown of Michigan's riser


The Big Ten's Rose Bowl chances don't look great even if you believe that Nebraska and Michigan haven't played up to their potential (and that one will get their act together). Purdue facing Stanford or USC would be brutal, and I'm not sure anyone would watch more than a quarter of Oregon/Purdue.
Edit: I guess the game would get plenty of viewers up in Eugene.
Go Blue!
