In terms of production, maybe. I admire Rick's effort on the glass last year, but he remained a one-handed player with a nice crafty up-and-under move but pretty average touch. AO could use either hand and was closer to automatic.
Regarding our guards next year, I agree with you: without someone who can routinely penetrate off the dribble, it's difficult to see too much offensive improvement. Perhaps CJ could add some driving ability, or maybe Carter-Williams ends up successfully getting into the interior of a defense. It's a big question mark, though.
