We all know what would happen... Guys would vote for their players, no matter how good they are, and then vote for the weakest at each position to kill competition... In the end, I'm affraid that the results would not be better than with the current system.
2 - Each user could vote for the best 3 players per position (with position being defined by BB and not by where the player actually played the majority of his minutes...). For example, the best PG gets 5 points, the 2nd gets 3 points and the 3rd gets 1 point. The process is repeated for all the positions in both squads, regardless of the conference in which the user is competing..Of course, you wouldn't be able to vote for your own players...
