Personally Bazz ran the offense just fine in the first half besides some sloppy plays. He definitely looked better running the offense than the other point guard. I loved that bazz's shot is back and he can get to any point on the court effortlessly. I even liked his fast hands on defense. He might have to find another NBA team to make it but he definitely has the talent to succeed at this level.
He's the one of two true PGs on the team, and Lillard was sitting. So he was definitely the only PG playing last night. But at his size I think it would be fair to expect him to facilitate the offense exceptionally well if he's gonna get a starting PG role in the NBA, and I don't think that has ever been something he specializes in, but he does seem to be thinking about it and working hard at it. And if he played with the same guys consistently, I don't see why he couldn't get there.
He was always a good passer and took pretty good control of the ball. If you're trying to blow people with a chance at real playing time for two nights then you're bound to get a little careless.
I don't think his size is truly a limiting factor for a true PG. Tons of guards have made it at his size and had great success. The Celtics are officially the top team in the East now and Thomas is a lot shorter than Bazz. It's a disadvantage, but it's by no means completely prohibiting.
