That's pretty much the talent level Syracuse is used to having with the occasional 3-7 year NBA veteran. Even a handful of games in the NBA is exceptionally rare for a college player. Since sanctions, it's been a parade of kids with either NBA size/athleticism and limited skills or decent skills but without the size/athleticism to really play the coach's offense and defense. It's obvious that while there are exceptions to everything - but the team has been overwhelmingly mediocre and more or less a plucky mid-major since sanctions relative to expectations for a top-10 all-time winningest program.
ETA: The emphasis is really the point here - there are good programs that take kids who will never sniff the NBA and mold them into capable teams. With the right players, JAB's offense and defense can be exceptional - but that is reliant on uber-talented players like Melo, Wes, Flynn, Rak, etc. Fab was never going to be a long-term NBA player, but in the zone with the right help, he was an absolute monster.
