Gov. Mark Dayton today named three Minnesota business leaders to lead the state’s effort to bring the Super Bowl to the state in 2018.  Former Carlson Companies CEO Marilyn Carlson Nelson, Doug Baker from Ecolab, and U.S. Bancorp’s Richard Davis will be in charge of developing a formal proposal for the NFL.  The league earlier named Minneapolis as one of three finalists for hosting the big game in 2018 and the NFL is expected to announce the host city in May.
