Is Frank Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!) or something? Irving is short, black, quick, decent passer, can create shots, and doesn't turn the ball over. Seems like a pg.
All I can give you is the "he watches all the practices" talking point. But Irving doesn't play PG much. If he was ever going to do it, it was toinight, and it was clear that Frank was doing everything he could to keep Sprads there as much as possible. Even playing Myles a bit in the first half to give Sprads a breather, then Irving did get a very short stretch at PG in the 2nd, before Sprads came back in for the final stretch of minutes.
I'm going to guess it's this, and this is just a guess. With this team, with no true point guard, all of these guys, Sprads included are shooting guards, Frank has to decide who is the most valuable at the 2 and the guy playing the point has to sacrifice some O to keep the offense going.
With this revelation I am going to give up a talking point. I thought the combo-guard look would work with this team like it did last year, but not quite as well. It is obvious that the combo-guard positions only work when one of the guys is an actual point guard.
