I actually like...
Unit 1:
-------
C: Amir Johnson
PF: Jonas Jerebko
SF: Jae Crowder
SG: Avery Bradley
PG: Marcus Smart
That's one very athletic and scrappy team that will never get beaten to a loose ball. Every player can defend multiple positions (excellent P&R coverage) and every guy can step out and hit the three, and it be murder in transition.
My only question is whether this rotation can hold it's own on offence.
I think this roster would really wear down opposite teams with all the switching and physicality on defense...then after the first unit tires them out, the second unit comes and throws all of the punches offensively.
Unit 2A:
-------
C: David Lee
PF: Kelly Olynyk
SF: Evan Turner
SG: Terry Rozier
PG: Isaiah Thomas
With this lineup you are applying constantly offensive pressure.
You have David Lee, who can either post up (against smaller defensive opponents) or step out and hit the midrange jumper (against bigger/slower frontcourt players).
You have Olynyk and Thomas - both of those guys are a threat from the three point line and off the dribble, so it's hard to decide how you're going to defend them. You can't sag off or they'll shoot the three, and you can't play them tight or they'll drive by you.
You have Turner and Rozier who can create off the dribble and drive right into the heart of the defense, forcing them to collapse - and they can both hit the pullup jumper from midrange if the lane gets clogged.
Every guy in this lineup can also pass the ball, so you'd have a lot of dizzying ball movement. Drive, dish, drive, dish, drive, dish. Keep the defense on their toes, until you can generate an inside pass to Lee, or a perimeter shot for Thomas/Olynyk.
Unit 2B:
-------
C: David Lee
PF: Kelly Olynyk
SF: Evan Turner
SG: R.J. Hunter
PG: Isaiah Thomas
Basically the same deal as unit 2A, but this is the unit you put in if you want a bit more pressure on the perimeter. Instead of having three attackers (Turner, Rozier, Thomas) and two shooters (Olynyk, Thomas) you go with two attackers (Turner and Thomas) and three shooters (Olynyk, Hunter, Thomas).
Still works similar, because you still have 5 skilled passers and ball handlers in the game.
I think these rotations could be an interesting look, and could make us very difficult to gameplan against because the first and second unit are so different.
Unfortunately for these, Sully doesn't really fit either approach. He's not agile enough defensively, isn't capable enough off the dribble, and isn't dangerous enough from the perimeter, for him to really complement either of these lineups. He has the skills to fit the "inside man" role on the second unit (like Lee he can rebound, score in the paint, and his the midrange jumper) but the problem is that Lee simply plays all parts of that role better than Sully does.
So Sully kinda becomes...redundant...in these rotations.
