Thompson dominated the glass against the Warriors last season, I think you're misremembering things, they were guarding Mozgov one on one and were basically like
if he scored. Thompson on the other hand did give them a lot of trouble, he had 32 offensive rebounds in that 6 game series, for comparison Adams had 22 in 7 games. They could not keep him off the glass last year, and while Love is
on defense he is another excellent offensive rebounder. The Cavs pose a different thread because a lot of their offensive rebounds end up being 3s.
Love is the sore spot for the Cavs offensively, but he will pull someone from the rim and give Bron the driving lanes he didn't have last year.
