Republican Gov. Charlie Crist is breaking out the big guns in his Senate primary with former state House speaker Marco Rubio.

On Wednesday, Crists's campaign announced the backing of former Miami Dolphins coach Don Shula.

“Florida voters can trust Charlie Crist to fight for their interests in the U.S. Senate,” Shula said. “Gov. Crist’s conservative policies have kept our taxes low and allowed our businesses to thrive, and he has the character it takes to work first and foremost for his fellow Floridians. Washington needs a leader like Charlie Crist to stand up for Florida in our nation’s capital.”

Shula is the winningest coach in NFL history and won a pair of Super Bowls in 1972 and 1973. In other words, he's a pretty big deal in the state.

Former Chicago Bears Coach Mike Ditka failed to tip the primary scales in Illinois earlier this year. Can Shula do any better?
