Former Minnesota Viking Robert Smith will be back in the Twin Cities later this week for benefit concerts with the Minnesota Orchestra for the Robert Smith Foundation. Smith suddenly retired as the Viking's top running back after last season at the age of 28, passing up millions of dollars in his next contract. Smith was a pre-med student in college, and started the foundation 2 years ago to support children's hospitals and cancer research. He spoke with us about the foundation, his retirement, and Randy Moss. He said his foundation raises crucial money for effective cancer research.
