Brad's teams always struggle against teams with size. Reese has 25 pounds on Morez and 20 on Tomi. This was going to be a loss one way or another. The three-point explosion makes it a blowout.
When the players you're trying to beat are wider, they can more easily block passing lanes. You have a harder time driving past them, and with the post players, a harder time getting a shot past them.
We really rely on quickness, cuts, kickouts, and offensive rebounds. Every bit of that becomes harder when the lane is clogged.
