Mitchell has been schemed out. Kawhi and PG has been schemed out. It almost always gives advantage to the other players. It's on others to take advantage.
Remember the sentiment when Clips first busted out the zone. We all thought that wasn't sustainable because Jazz have great shooters and that threat opens up driving gaps that we can attack plus Rudy is there if they miss. It didn't happen though, Jazz got stagnant, played iso ball and no one stepped up consistently. Rudy has his limitations on offense for sure but he still has his gravity. When we attacked the rim 3-4 times, he got putbacks, when we don't he battles 2 guys plus guys crashing down from perimeter. It's not really possible to get offensive rebounds if guards can't break down the defense.
On defense. It's just the nature of perimeter defense. Simmons, the best perimeter defender in the league right now, gets 39 put on him, Kawhi looked ridiculous against Mitch at times. Giannis got punked, Jrue turned into Bledsoe. Everyone gets scored on the perimeter and Rudy doesn't even have the benefit of rim protection behind him. He is still playing great defense. Guys score it happens, Jazz need better defense from everyone else. Just like Mitchell can't carry the whole offense, Rudy can't stop everyone.
