In RL, a all-rating 99 senior would not shoot 39%, no matter what defense was thrown at him. He'd take good shots and pass out of double teams for frequent assists. Until HD makes such players much more rare (they simply don't exist, not even close, in RL, even a pro-prime-of-career Michael Jordan or any other player you care to name, is not 99 in all categories, not even close) and much more consistently effective, player generation will continue to be less than optimal.
