There isn't. The race is for 2nd.
Both Zach Edey and Trayce Jackson Davis are having extraordinary years. They are both legitimate candidates for CPOY and NPOY.
A one person race can longer be stated as a given because of statistical output--The numbers are pretty much identical; in conference play Trayce has better numbers in four of five stats and one of two key (points and rebounds) stats, for the entire season Edey has better numbers in the two key stats and Trayce is better in the other three (assists, blocks, and lower turnovers).
It's no longer because Edey is on an extraordinarily more successful team. The media votes on these things and they are noting a change. Here are Katz's current national power rankings. I am assuming that he is a media rep that will vote on at least CPOY:
1. Houston (2): The Cougars are atop my power rankings and deservedly so after holding serve in the American.
2. Alabama (4): The Tide beat rival Auburn and are still undefeated in the SEC.
3. Purdue (1): The Boilermakers drop down after falling at Northwestern.
4. UCLA (9): The Bruins got a sweep in Oregon and are the clear favorite to win the Pac-12.
5. Indiana (8): The Hoosiers followed up the Purdue win by beating Rutgers and winning at Michigan.
6. Texas (5): The Longhorns are currently atop the loaded Big 12.
7. Virginia (22): Controversy aside, the Cavaliers appear to be the best in the ACC — for now.
8. Baylor (10): Look out for the Bears, who are storming back in the Big 12.
9. Marquette (13): Shaka Smart is the Big East coach of the year.
10. Miami (30): The Hurricanes are playing their best basketball at the right time.
