There's something mental going on with Cody. He has two modes: one where he tries to be aggressive offensively, and one where he basically checks out if he knows he's not going to get touches. Who knows where his confidence is at these days, but he'll go from attempting an aggressive drive and high-level finish on one play to then barely looking at the hoop for long stretches. In that sense, it might not be a bad idea to send him back to the Gleague for more reps. However, I think the Jazz are letting him take his lumps while they're trying to secure some losses on the schedule.
If other guys are going to jack up shots with low efficiency and be careless with the ball, like Keyonte, Brice and Svi were the other night, it shouldn't be a problem to let guys like Cody and Elijah take a few more shots too.
