Not sure I follow the purpose of taking both Qi and Maker -- very similar projects.
And if you're going to take Dunn, I can't see I see why you'd trade Bradley. He plays off the ball, without it in his hands, effectively. That's not Dunn's game. And Thomas has proven he can play off the ball effectively, not to mention Dunn's size allowing him to play SGs on the defensive end while IT handles the PG.
You trade Smart (if you can get any value). Smart not very effective offensively regardless, but he's a total waste at the 2. And yes, he's a bulldog on the defensive end. So's Dunn. So's Bradley. So's Rozier, with any luck. A mix of Dunn, Bradley, Thomas and Rozier makes much more sense than Dunn, Smart, Thomas and Rozier (not a single one of whom is a natural SG).
A three man weave of Dunn, Bradley and IT, with spot minutes for Rozier? That's nice.
