Yes, to be the conference coach you don't need to know the skills players, one time the pre-list of more voted players is conclued position by position like fans think.
The coach will analisys player performances and stats and decide who pick to roster and line up.

And to Dunk Contest,
Max 6 players with:
More 2pts made [FG - 3PT]
More than 6'4" [to eliminate de small shooters]
I believe JS, JR and Stamina decide on 3pt challenger, to Dunk, in my opinion, we need HA, DR and IS.
