Marcus Coker was tremendous last week, but Adam Robinson wasn't chopped liver

The dismissal of Iowa running back Adam Robinson may have surprised some of you (good grief, why?). My gut feeling is he was gone before last week's arrest in Des Moines for marijuana possession. I can't base that on anything concrete or even flimsy. It was just a feeling. We'll probably never know.

But you don't get left behind on a bowl trip and then get arrested for anything without going bye-bye.

Marcus Coker tore Missouri's defense asunder in the Insight Bowl with his Iowa bowl-record 219-yard rushing game. But depth at running back -- a misnomer at Iowa no matter what preseason depth charts look like -- tell us Robinson is no small loss.

He had 834 rushing yards as a freshman, 941 as a sophomore. In 2010 he became a weapon catching passes, with 24 for 290 including one against Michigan State for a 32-yard touchdown, and a huge catch-and-run for a first-down to basically secure a win at Michigan.

But it's "Next Man In" at Iowa again, or "Next Man Up" as ESPN announcer Matt Millen kept saying during last Tuesday's telecast of the Insight Bowl.
