First there appears to be an unrealistic assumption that AA teams are very position specific. Sometimes they have two point guards or two centers etc. I agree that many voters may consider that, but others tend to select the 5 best players regardless of position. So if the second best at any position is clearly one of the best 5 players they can still make it.
In addition one of the AA teams just picks 10 players, without distinguishing between first and second team status. If you make that team once, you get on the wall, so first team status is not a strict requirement.
Third if you are very efficient on a very good team, you don't have to put up anywhere near the nominal numbers of points/rebounds/or assists per game to achieve AA status. Another reason for that is great players on great teams are frequently sitting for the last few minutes of blowout wins.
The national leader in Points/Rebounds/ and Assists per game, rarely plays for a championship contender.
