Just watched ECU/Florida from earlier this year. A few thoughts on Johnson.
1. I don't know if it was the camera angle from what I was watching the other night or what, but I was wrong on Johnson's height. He looks like a legit 6'8, and pretty well put together. Definitely a 4, imo, not a 3.
2. Athleticism is still a concern. Only took 6 shots and I think a good part of it was he wasn't able to really create on his own against Florida's size and athleticism.
3. The shooting looks legit. 3/5 from 3 and 1 of them rolled all around the rim before coming out and the other was a force late in the game with the clock running down.
4. Showed good rebounding position and effort.
Overall, I'd still rather Brown-Jones, but wouldn't be mad with him. Bethea, Pack, possibly Dinkins and this guy would create some absurd spacing.
