His compe ion is Tre because the open spot on the roster is for the backup PG/shooter spot that Mills has occupied for like eight years. If the Spurs somehow run with the guys on the team now. this would be a projected depth chart
Murray, Jones
White, Walker
Vassell, Wieskamp
Johnson, Samanic
Poeltl, Eubanks
Weatherspoon and KBD are both RFAs and thus could be back. In the very least, I'd want KBD back to add depth at the three and four. Regardless, the backup PG spot is the one with the least compe ion. There are no first-rounders, vets or better-sized players at that spot. It's not that Jones can't hold onto the spot (I actually expect him to be one of the better SL players in the league this year). But if we're talking about replacing Mills, then nothing is keeping Primo from getting minutes but excuses. It's abnormal for lotto picks to be frozen out by second-rounders and min-salary guys. Primo doesn't have to start off better than those guys, but he'll likely not embarrass himself against them either. And if he can take those shooter minutes while he grows into more, that makes the most sense. Well, it'd make the most sense to trade Murray and start White, Vassell, Johnson and a real PF, sign an expensive backup PG and a solid backup center, and then let Primo, Walker, Wieskamp, KBD and Samanic fight to sort out the middle of the bench. But you take what you can get when it comes to PATFO.
