It's tough to make stats work on a guy who hasn't played but a handful of games this season in inconsistent situations.
This season is not the same as last by any means. The supporting cast has changed enough to alter rotations and change the identity of the team. Most importantly, the coaching staff and offense has changed. It's had an impact on certain players more than others. Our best players regressed. It took a large number of games for Fox and Buddy to find their footing. Dedmon, who was supposed to be the complimentary big man to Bagley, never got a shot to play for whatever reason.
Bagley had played 13 games, including the games he was injured in. Not to mention, when he came back from the broken hand, he was wearing a brace that affected his shooting, was playing with a different unit than he spent training camp and preseason working with and the coaches had decided they weren't going to be a running team anymore. Bagley gets injured again, comes back and starts to play better all around after he gets a good couple of games under his belt, then injures the same foot again, which means he wasn't 100% healthy when he came back to begin with.
His health concerns are fair, as is the job of this training staff. But there is almost no consistent foundation on which to base his stats on for this season.
