It is hard to say what attributes are overated without seeing the related attributes (ATH, STA, Off./Def. Ratings) for a team/player, as well as the Off./Def. Scheme that the team is running. All attributes are elevated with each of the compounding attributes that I mentioned.
If you have a team with each player possesing a 90 LP and 90 REB and only 5 ATH, they are most likely not going to rebound very well. They also won't be able to score at will inside the arc. It would be very easy for a coach to recognize this and have a strategy to exploit it.
I think it is important to learn what the all emcomposing, booster attributes are before you ask this question. If you have a team with each player possesing 60 ATH, 60 REB, and 60 LP, I am very confidant they will be an elite rebounding and FG% team.
Keep in mind that each Off./Def. Scheme will require different importance in attributes as well. Some will require more even BH, PAS, PER, LP while some will require more BH, and PER. Within an ever growing simulation model, you have to understand that every single attribute is meant to be an equation that equals into a specifc result after it is run through the simulation model.
I realize this might seem to be a broad statement in regards to the originak question.
