March Madness best bet: Auburn to win title
The Auburn Tigers are about as complete as you can get as a team, with a strong mix of elite talent while also boasting a lot of experience. They are led by national player-of-the-year candidate Johni Broome, who can do it all, averaging a double-double.
Behind Broome are four guards averaging double figures, with each shooting 37% or better from three. As long as they remain healthy, the Tigers are a solid bet to win it all.
