My fear is that when I watched him he wasn't really a rim protector. How much of that is due to Texas' roster and Sims I don't know. But the worst case scenario is that he's essentially a big wing instead of a center.
He's switchable like Bam but they aren't all that similar as prospects. Adebayo was shorter/stouter and more of a traditional big while Jones did more work on the perimeter
I think that in some ways, Jones is being blamed for how he was used. No, he didn't play like a traditional center, but then they had Sims representing that group. So if you want to get both Sims and Jones on the floor together, and Jones has some game away from the basket, then he ends up playing most of the time on the perimeter. Despite playing away from the basket, he put up similar per 40 numbers as Sims, except for rebounding, which makes sense. Both players averaged around 1.7 blocks. Also, remember that Sims was a senior and Jones was a sophomore.
Sims played just over two minutes more a game than Jones, but some of that was on Jones, who was in foul trouble a lot. Someone suggested that he had trouble finishing over players at the basket. That was actually something he was good at. Running the floor and dunking over defenders. There's no doubt that he's still on the raw side, but he has all the tools to be a very good NBA player. He's probably two to three years away from reaching his total potential.
