1) Allonzo Trier (Arizona)
The best player on one of the NCAA Championship favorites, Allonzo Trier tops the list of best returning players in the Pac-12. His decision to return to Arizona followed a season in which a failed drug test caused him to miss half the season with a suspension.
Despite the early setback, Trier emerged as one of the best players in the country, leading Arizona to a Pac-12 Title and a Sweet Sixteen appearance. In his 18 games last season, Trier averaged a team-high 17.2 points, adding 5.3 rebounds and 2.7 assists.
These numbers increased in the Pac-12 and NCAA Tournaments, during which he averaged 18.8 points, 6.0 rebounds, and 3.0 assists. His performance led some to consider him the Pac-12 Player of the Year, despite missing the first six conference games.

Entering this season, Trier is poised to play a full season and continue his performance from last season. If he plays to ability, he will be a contender for the NCAA Player of the Year and a potential lottery pick in the NBA Draft.
