There aren't too many different flavors in the Sweet 16.
Only four conferences are represented. It's the first time in NCAA tournament history the Sweet 16 is made up of all power conference teams. The only seed lower than a No. 6 still alive is No. 10 Arkansas. The Razorbacks, with its massive NIL budget coming from the powerhouse SEC, are not a fun underdog story. They were just underachieving for a few months.
However, the favorite-heavy first weekend does lead to one of the strongest sets of Sweet 16 matchups you'll find.
