I agree with DJ. At least two of those turnovers were bad plays in which he telegraphed the pass and tried to force it inside to Big Al. AK made the same mistake as well. So, that's three turnovers that were bad plays and at a crucial time in the game. The observation about no outside shooting is valid. CJ was off, and there is no one else who can come in and reliably deliver from the outside. Maybe when Memo comes back that will change.
A 2-3 minute break for Deron isn't going to lose the game. In fact, the Price and Watson combo bring in a burst of energy that usually helps. It's a judgment call on Jerry's part, not anything egregious, and I think he will adjust.
