JJJ almost never “disappears”. He just doesn’t always get his points or other stats. But he’s always contributing something. Getting into passing lanes and initiating steals that he doesn’t get credited with. Altering shots but not being credited with blocks since he didn’t touch the basketball. NOT turning the ball over while touching it many times during possessions. Helping out on defense. Also playing great defense WITHOUT fouling.
On any single possession, generally only one player out of 10 can be credited with a basket or a rebound or an assist or a steal or a block. That doesn’t mean that the other 9 players have disappeared. There’s a reason that JJJ might have the fewest points while having the most minutes. The coaches see it.
It’s fair to claim that he “dissappears” from the points line in the box score. But he’s also an unselfish, pass first player working alongside one of the most aggressive scorers in UT history. It isn’t going to work if the lineup is all shoot first players.
