I'd rank their performances as something like this:
1. Olynyk
2. ...
3. ...
4. Smart (Except when he was playing off the ball as SG -- swap him with Pressey then)
5. Pressey
6.
7. Johnson (Quiet & not utilized much, but actually played mostly very solid on D and in control within the system. Made some smart plays that were reminders of why he 'stuck' during the regular season).
8.

13. Everybody else.
Seriously, I don't really see anybody outside those 4 as being NBA-ready yet if ever. I saw a huge gap in talent between Olynyk and everyone else. Smart showed spots of fantastic potential (especially when he was on D or on-the-ball, driving to the hoop) mixed with typical rookie mistakes and awful 3PT shooting. Pressey was also inconsistent, showing some great court-awareness and leadership on some plays and then bricking awful shots on others. And Johnson, as I indicated, was quiet, but showed at times why he's at least on the boundary edge of the NBA.
I guess I'd count Moser as the best of the rest. But he looks like Maine RedClaw material at the moment. 'Probably at least worth bringing to training camp, I guess. 'Need bodies.
