Yeah, it only took terrible Lue a game 1 shellacking to make the right change.

Love at center was always a dumb move given how terrible it made their interior defense. Cleveland's biggest advantage over us in the past has always been their size in the frontcourt with Lebron, Love, and Thompson, which we simply couldn't handle in the past. Just look how much Thompson killed us on the boards in his short stint yesterday. Granted, things are a bit different this year with Baynes, along with Big Al playing the best ball of his career.
This puts Brad into an interesting position. I'm not sure what the right lineup move is. Keeping Morris in the starting lineup will certainly create even more mismatches on the offensive end for us, but I'm not sure how to matchup defensively. If you keep Morris on Lebron, which is the main point for him to be in there, that would leave either Tatum or Al on Love. I'd rather Al be on Love, as I don't see how Tatum can guard Love on the post, but on the other hand Tatum will be eaten alive on the glass by Thompson.
If you go back to Baynes, that means either Morris (your main Lebron defender) or Tatum (your leading playoffs scorer) has to come off the bench, which is far from ideal.
I imagine we stay with Morris starting for now, put Al on Love and Tatum on Thompson, and try to mitigate any rebounding issues through a group effort of crashing the boards. And if that doesn't work, I imagine Brad will substitute early and go bigger with Baynes. We just have to hope we can take advantage of our mismatches on the offensive end by staying small.
