Zach LaVine saying Rudy Gobert is "not going to get 30ppg, he's a defensive guy -- that's his job" is him telling on himself. The subtext there is "that's not my job -- my job is to score" and it shows in the way he plays.
This is a huge problem. Because if we have guys who are going to self-identify as offense only players and other guys who either by choice or lack of opportunity have been pigeon-holed as defense only players than Doug's choices here are: (1) Bench all of the guys who don't think defense is their job. Yes that means you Zach. (2) Continue to watch the team get blown off the court.
But I also have to acknowledge that Doug is really backed into a corner here. The 5 highest paid players on the team are also the 5 worst defenders and of the 12 guys who played in this game, 8 of them are guards and the other 4 are centers. Just like last season when Monte McNair somehow thought a frontcourt rotation of Domantas Sabonis, Alex Len, Trey Lyles, and Isaac Jones was good enough to make the playoffs, Scott Perry didn't finish his part of the job and has left his coach with the unenviable task of trying to juggle playing time for 6 different guys who all play the same position and build a winning team defense without any NBA forwards.
