Better defense and passing than Lauri could dream of. Kevin McHale was on 8 all NBA teams. Those are generational superstars. Lauri has potential to be great, but that's an insane comparison. The NBA has more talent and parity in the league today than ever before, including the 80's.
Vando could've started for those Celtics as a 4, maybe, and be fine. It probably would've fit his game pretty well. Today's game is not kind to nonshooters unless they are a top 5 defender, and Vanderbilt isn't that.
