Not surprised, we are inconsistent for several reasons:
Isaiah Thomas makes it impossible for us to play good defense. The switch is forced, Amir/Al come over to help, one pass, two pass, defense collapses. Our you can just drive/ get essentially a wide open mid range look on 5'5 Isaiah.
We are a jumpshooting team, which means we rarely get reliable looks at the rim. If AB bricks like he did tonight, and Jae just forces threes and misses, we are in for a rough night.
Our players, besides Isaiah can't really create on offense. Isaiah has no choice sometimes except try to bail us out with hero ball, because AB and Jae can't create looks for themselves. Its not like we can find Jae in the post, or rely on AB to pull out a dribble move. Al in the post is not a reliable option either anymore.
Wall, Beal are a multidimensional team, with a pass first point guard and several players that can create for themselves. Also they are never really in a 4 on 5 defensive situation that we are often in.
