I believe the Big 12 criteria for All big 12 is 3 guards and 2 posts. With that in mind we have more dominate guards this year then post players which is unlike the league. If I was picking the 5 best players based on team importance and performance it would be different from how I think the voting will go down.
I think there are 4 guards fighting for 3 spots. I left Cousins out because he gets outshined by his own teammate but he's just as important to OU as is Hield. With really no dominate SF I think 3 backcourt players will be picked. Staten is probably ahead of Mason on reputation alone but you definitely can argue Mason has been more valuable. He will probably need WVU to tank down the stretch to go ahead of him.
In order
Hield
Forte
Mason
Staten
Posts I believe 2 have seperated themselves with consistent play. Nash gets less votes because of Forte and Ellis hasn't been dominate enough even though he's the quiet leading scorer of the team. Realistically 3 guys fighting for 2 spots.
