I also think people are sleeping on James McAdoo a bit. Terrific athlete, good size, good skill level, great BBall IQ. He offers a nice compromise between the strengths and weaknesses of the other three great PFs in the class.
Like TRob's motor and athleticism but don't like his BBall IQ and level of finesse? McAdoo is a good compromise. Like Davis's offensive game and athleticism but don't like his body type? McAdoo is a good compromise. Like Sully's IQ and finishing skill around the basket but don't like his level of athleticism? Again, McAdoo is a good compromise.
He doesn't do any one thing as great as the top three PFs in the class, but he does all of the things better than any of them. If we miss out on the top three guys at the position, McAdoo is our best remaining option--if he declares.
