Kanter has played less than 10 minutes in only 5 games this season. All of them have been in the last 10. Over those 10 games, these are his stats:
23/35 FG (8.0/12.2 per36); .657 FG%
6/8 FT (2.1/2.8 per36); .750 FT%
.675 TS%
10.3 mpg (103:05)
18.2 Points per36
10.5 Rebounds per36 (12-18-30)
2.1 Assists per36 (6)
1.0 Steals per36 (3)
0.3 Blocks per36 (1)
3.1 Turnovers per36 (9)
3.1 PF per36 (9)
Most of Kanter's efficiency comes from easy weak side putbacks. If the Jazz can run then Kanter clearly should play over Jefferson. If they can't run then it's tougher to increase efficiency wtih him in the game.
I'd also like to see more cleanup by design plays when Jeffy is on the low block. He could throw up a shot over a triple team and call it an assist if Kanter is in the vicinity bearing down. Kid has a ridiculous nose for the ball, even in long rebounds which is much rarer.
