The NCAA launched its "Frozen Four's Finest" social media campaign this week, designed to let fans vote on which team was the greatest NCAA champion in history.
The 16-team bracket features national championship teams from 16 schools. Voting is set from 12 to 9 p.m. ET each weekday through Oct. 3 as excitement builds for the 2014-15 season.
Fans can vote for their favorite teams using specific hashtags during each matchup.
