Lee isn't a bad m2m defender. Its everywhere else he's terrible. Similar to Bargs who is (or used to be) a good post defender but horrendous everywhere else
Gasol was one of the top post players in the league this year from an efficiency standpoint and he's been really strong this postseason from the post. Tonight seems like an outlier for him more than anything. Never a guy that'll dominate a game but he's definitely someone that if not doubled will normally kill you on the block
