Yes it has.
But this may be a different animal this time. The numbers Davis has put this season are staggering, at least in an efficiency perspective. Cuz STILL is producing more per minute, but Davis, really every since he and Reke were finally teamed up late last year, is just doing it so easy. 56% shooting, no turnovers, no fouls, stl/block numbers like an offensively skilled Kirilenko.
One interesting and encouraging note though: the one game when he got shut down? Precisely his game against the big physical Memphis Grizzlies where he was once again the skinny finesse player getting bounced by the full grown men. And this season we might be the team in the league who resembles Memphis the most. Big physical frontline, no 3pt shooting, surges of exceptional defense etc. JT has to stay out of foul trouble though, because he's been a big key against Davis, and I don't see anybody else on the roster who could slow him except Cuz, who obviously needs to be shielded from fouls if possible.
