From the Minesotta vikings home page:
In Linehan's first year in the NFL, several Vikings set individual marks. Second-year RB Michael Bennett ran for 1,296 yards, which was the 2nd-best single season performance in team history, and was named to his first Pro Bowl.
IF he has used so many runninbacks is because his feature runninback (bennet) was injured, his replacement (Onterrio Smith) was out 4 games or more for substance abuse, Moe Williams was more of a bruiser than anything, and Mewelde Moore well no one actually thinks he can be a full starter, so he played around between backs, but you cannot tell me that is how a Offensive Coordinator gameplans based on only one season. Bennet carried the load, and after him Moe Williams did in the 2003 season, at least until Onterrio got healthy, plus we should even go as back as what he did in Louisville, (i could not find the stats), he did use multiple runningbacks last year, and he will if that is going to help the team, but that does not mean that he will remove our best player of the field (if ronnie turns out to be that) basically because his style is to run different backs.
