Brown doesn't really have much of a BBIQ, but he can be competent if he is given an assignment that is within his abilities, it is a simple assignment, and he doesn't have to make a lot of other decisions on the fly. That has really been the secret of his limited success (and his failings) with the Cavs thus far. He can run the floor and get lobs, he can do the pick and roll, he can rebound, and he can block some shots. He can't do much else offensively and defensively without extensive coaching and time for repetitions and is going to have trouble making in-game adjustments (hence the problem when Bamba started making threes).
Honestly knowing what you can do and doing it consistently is a very useful thing. Plus the list of skills you laid out there is a fantastic list for a backup center. I mean, that’s all Andre Drummond can do well too
