You can't put much into the season stats. Like someone else already said, the majority of his competition this year were cream puffs.
With that said the game he had last night was (IMO) the best singular performance we've seen this season. We've seen better (points) offensive performances. We've probably seen a few defensive performances that were better. But I don't think we've seen a player shoot that well, be that efficient, rebound well, defend (cleanly) that well, shoot FTs, hit 3s, basically do everything you'd want out of a position so perfectly WHILE being our clear go to player in a particular game. It was not just an elite performance, but an efficient elite performance.
It was easily the best game of Jaz's career at a time we needed it. If Gabe and Grill can get (mostly right), Lipsey cuts down on the TOs, and guys lay off the stupid fouls, we have can have 6 guys (Shoon, Grill, Gabe, Lipsey, Holmes and Jaz) that can lead the team in scoring and have a solid double digit threat guy in King (edited). We lack athletes and shot creators, but the balance can help mitigate those deficiencies. It's tough though when only 1 or 2 guys are being reliable/efficient, which was the case last night.
TBH, I expected Jaz to be a lot rustier than he has. Not only is he not rusty, he's probably been our best player these last 2 games (definitely last night). While the sample size is flawed, last night makes me think Jaz has taken his game up a notch. Couldn't have come at a better time.
