Adam Robinson left Iowa coach Kirk Ferentz with very little choice.
After a period where Iowa's off-field problems were placed in the national spotlight, Robinson's arrest last week for marijuana possession essentially sealed his fate with the program.
Ferentz made it official Monday, dismissing Robinson from the team.
Although the incredible performance by freshman running back Marcus Coker in Iowa's Insight Bowl victory against Missouri softens the blow, Robinson's departure still stings the program. You could argue he was the team's offensive MVP for much of the season, taking the bulk of the carries as the team's only healthy proven running back.
This is a very unfortunate ending for Robinson, an Iowa native who surprised a lot of folks with his skill and toughness in two seasons as the team's featured back. He rushed for a team-high 941 yards and 10 touchdowns this season despite missing two games because of concussions.
Ferentz suspended Robinson for the Insight Bowl in early December for unspecified reasons but sounded confident that the sophomore would rejoin the team this month.
Robinson's arrest changed matters. What a shame.
Running back depth once again will be a concern for Iowa entering the 2011 season. It's amazing to think that Iowa entered this fall with three proven backs -- Robinson, Jewel Hampton and Brandon Wegher -- and all three are no longer part of the program.
Coker will enter the fall as the team's only back with much game experience. Although Coker has all the ingredients to be a star, Iowa really needs others to step up.
