Entering the 2021 NCAA bracket, seven different seeds have cut down the nets since the field expanded to 64 teams in 1985. As you would expect, the No. 1 seed has won the most (22), followed by the No. 2 seed (5) and No. 3 seed (4). Four other seeds each claim one championship, but conspicuously missing among that group is the No. 5 seed. Every other top-8 seed in March Madness 2021 has won the NCAA Tournament at least once, so is No. 5 finally due to hoist the championship trophy?
