Actually I have Harris as one of my dark horses so I don't want to belittle him. I think he was hurt somewhat by having to play out of position. However, I don't think Singleton is a poor offensive player. When I think poor, I think Michael Smithish. He's not a guy thats going to jump up and suddenly give you 15 a night, but I think he can easily, with the minutes, give you 8 to 10 points a night, and be a lockdown defender. Since I believe thats what Westphal stated he wanted from his SF position, I have Siingleton rated as high as I do.
I was by no means trying to disparage either player. Just simply pointing out how a team might look at each player, and how they might judge them. Harris if one of those guys that three years from now, might be top 5 pick if the draft was redone. By the way, Singleton shot 36.8% from behind the arc last season, after working hard on his 3pt shot in the offseason. And while his 67% freethrow shooting definitely needs improving, his percentage has improved every year he's been in college. Harris shot 30.3% from the three. But as you said, he's very young, and playing PF last season didn't help him much.
