Personally, I respect Fred's honesty. Brackins probably saw his stock drop year-over-year, not to say there weren't a lot of factors in that, but it happened. So treat that statement as one of "fact" not of "opinion".
That being said, look at Draymond Green at MSU. He is the most similar player, IMO. Last year he had to handle some point responsibilities, and this year he's been able to focus on the block. I think best case scenario for RW IF he comes back is to show great post work, respect the 15 footer AND run point a minority of the time to frustrate opposing teams. He could legitimately average a double-double by primarily working from the block and off of pick-and-rolls. To me, that's the primary area for upside. Secondarily, he can work on his defense (not losing focus and not getting pushed under the rim on the entry pass) and his free-throw shooting. Although, both of those things aren't numero uno in the NBA.
I'd love to see him come back and take this team deep next year. I can't imagine staring at a million dollar decision like that at his age. I just hope this doesn't really ramp up his anxiety and he's able to stay level.
Tremendous amount of stress to be under - high-class problems, but stress all the same. Just as Royce has continually been selfless this season, I trust Fred and the cyclone community will do the same. We'll support him either way, he's earned that.
