Without beating a dead horse on Johnson, his season was really disappointing. The exit is a red flag in the eyes of many, as he prematurely took himself out of the year to rest his body and prepare for the draft. Immediately after, Duke went on a mini-run to prolong their NCAA Tournament hopes.
When Johnson did play, there was something readily apparent: he lost all athleticism and impact when playing in the half-court. I don't know how to explain, or cure, something like that other than to find ways to get him to play in space more often. But playoff basketball is played in the half-court, and you draft in the top-end to find playoff-caliber starters. I'm not sure where Johnson lands, but he might be one of the most divisive prospects in this year's class.
