I agree that he'd be starting quickly, not just because he's talented enough, and needs the experience, but also because the economic reality is that the fans need something to be excited about ASAP. Our top draft pick this summer is going to be it, so I don't think there's any way they'll let him spend much time on the bench.
And this should be nothing strange or controversial, even back in the stone age when we got our last great draft picks, PG Nate Archibald started all 82 games as a rookie, playing 35 minutes per game. Oscar Robertson played in 71 games (out of 79 in the '60-'61 season) as a rookie - obviously he started virtually all of them, since he played an average of 42 minutes per game. And other franchises routinely did likewise. The rookie Jason Kidd started 79 games, @34 minutes per game. Isiah Thomas started all 72 of the games he played as a rookie, @34 minutes/game. That is normal for a very talented rookie PG in the NBA.
