Hall saved our bacon a lot this season, but he's at best an average Big12 PG. He'd be a LITTLE better than that if he were a 80+% FT shooter — but even then, I doubt KY wouldn't have recruited beyond him for an Egor replacement.
No team is talented enough to afford only an adequate PG in the starting group. You need one that gives you special speed or passing, or even shooting. A PG in Dallin's mold COULD qualify — but he'd have to be impeccably clean & efficient. Which Dallin is not in danger of becoming anytime soon.
