This is just my hunch, but I think we saw phase one of JB’s plan to play a 4 guard lineup in a lot of situations.
The four guard lineup might work even better with Brooks instead of Z but JB probably wanted to protect Brooks from the possible confusion of the changeup. But maybe not because transition is dependent upon deflections and turnovers, to some extent, so perhaps a four guard lineup would be best suited for Z.
MAAR was taking the 4 spot offensively when there was a chance to push the pace and when he was the first able to get to the spot.
I would not be surprised if the four guards are going to push the pace, Look for quick 3’s, then, just “play ball” for the first few seconds of half-court/ late transition, if nothing happens they will set up with everyone in their ideal positions. The goal, I think, is to have 4 players who can run the floor well, hit transition 3’s, And be playmakers in late transition.
Brooks, Poole, Matthews, and Maar are all fast and capable in transition, capable ball handlers and all 3 point shooting threats.
If the emergence of Poole is a real thing it is going to really be a game changer, imo. And I expect this team to be a lot more fun to watch than the last few years…
+MO= electric lineup.
