Alan isn't 'bad' at all. At least not on an Olympic-medal-contender-bad. Wallace is (or was) just better, at least when he performs at his peak. Wallace didn't reach his peak enough during this Olympics and often times when Alan got the chance to replace him, his impact on court was nothing out of the 'ordinary'. But yeah, it was maybe right to let Alan play a bit more. He's going to be the starting opposite in the next Olympics though, no doubt about that. But this will likely be his last Olympics as well since he'll be 34 (same age as current Wallace) by the time LA 2028 arrives.
