Good post. But I think you mean "guys without wholes in their game don't EXIST. Guy's with less holes in their games start."
Delly get's shat on by the haters for having no handle and being a poor shooter. Both of which are great for a second year backup point guard that his wearing himself extremely thin by hustling more than anyone else in the league (4th AST:TO ratio, 14th 3PT%). He came back way too early from that knee injury and hist 2P% suffered as a result early in the season. But I think it will be up next year. I don't think many people who REALLY watch his game closely claim he is lacking those skills. Yet the casual people who show up to scapegoat like to say that.
I think the only thing he severely lacks is the ability to create his own shot all the way to the hoop. He can get that mid-range floater, but trying to take a man 1 on 1 he lacks hops and height.
you can't REALLY watch the game if you think Delly has great handles. He's a solid defender and a solid wide open shooter. However, not being able to consistently dribble well enough to create for others is a hole that is significant for a point guard, starter or backup. The Cavs are looking to upgrade the backup guard. It's not a negative to call Delly a 3rd pg.
