Why Arizona at 22%

Historical Edge

1-seeds win the title 22.5% of the time historically. Arizona's 93.1 adjusted defense ranks in the top 5% of all tournament 1-seeds since 1985.

Path Advantage

The West Region is projected as the most favorable for a 1-seed, with no other team above 5% title probability in their quadrant.

Matchup Profile

Arizona's defensive identity historically travels well in March. Elite defenses win 60% of tournament games decided by 5 or fewer points.
