As you probably know, all-conference teams will all be determined by the traditional 5 players in 1st, 2nd, and 3rd Team. The SEC has 9 players and Pac-12 & WCC has 10 players on the 1st Team. So, Win Shares will be the determining factor for the final four spots. The conference POY is automatically 1st Team. So, the next four are determined by the highest Win Shares. Also, the Big East doesn't have a 3rd Team. So, I also used Win Shares to determine the 3rd Team.

Iverson Molinar, Mississippi State- 4.8
JD Notae, Arkansas- 4.3
Quenton Jackson, Texas A&M- 5.5 (Wasn't voted on 1st Team like the 9 players above him, so 10th is his ceiling)

Kennedy Chandler, Tennessee- 4.6
Colin Castleton, Florida- 4.5
TyTy Washington, Kentucky- 3.9
