Without Book, we cannot create enough space for open shots. Brooks and Allen have only limited shot creating ability. Facing good team defense, Oso and Gillespie are ineffective. Also, we see Livers much better than Dunn on both O and D. Our 3pt shooters are too streaky and easily fold under pressure.
Phoenix couldn't get to the basket or create their own shot. Not much else to say about the offense other than they couldn't hit the broadside of the barn when they did get a good look.
The defense and rebounding wasn't there either but that's another story.
