Gobert's combination of length and speed makes him a problematic matchup: he's not strong enough to deny Cousins position in the post, but he's so freakishly long, that it doesn't matter. Against players where Cousins has a height disadvantage, he can usually face them up, and take them off the dribble, but Gobert is also one of maybe two centers in the league who's fast enough to keep up with him from out there. It's like, the only thing you can do to take him out of the game is to catch fire from outside.
