Another factor is going to be injuries. A number of teams that could be in the field have been hampered by injuries. Earlier performances and success may be overshadowed by key players lost for the season. How will the committee evaluate the potential of a team which is without a key star.
Here are some examples from the weekend:
I saw an injury firsthand as Georgia's Yante Maten suffered a knee sprain early in the game against Kentucky. Georgia was on the outside looking in, but losing the third-leading scorer in the SEC is a major setback. The Bulldogs fought hard but fell short to Big Blue. JJ Frazier with 26 points was brilliant in defeat for Georgia.
Michigan State, which has been plagued by injuries all season, suffered a blow when Eron Harris was injured. He required season-ending knee surgery. The Spartans were a bubble team and the committee will have to evaluate Michigan State without a starting guard.
Injuries are a part of the game.
