He guarded the second most fga on our team. So good on him for stepping up and taking on that challenge. I think he is a better on ball defender than off ball, so that was a good adjustment by Quin. He still isn't super effective. I'm not sure I would call him a liability, but you probably need much better perimeter defenders out of your other positions if you want to keep him next to Donovan. In my opinion, you probably can't play both him and Donovan together and have a good defensive team.
The reality is that to stop Luka, and any decent playoff offense, it needs to be a team effort. Bogey is OK on the ball and I applaud him for stepping up, but he is one of the worst off ball defenders in the league. He is always late to rotate, has no defensive range, doesn't create turnovers, falls asleep/ball watches, and also provides no rebounding at his position. It doesn't matter if you have Jrue Holiday as the point of attack defender....if you can't defend as a team the best offenses will destroy you. I'd agree that you probably can't have Don and Bogey on the same team and be a good defensive team. Both are iffy on the ball....Bogey is alright sometimes, Don depends on engagement....but they are both really damaging defenders off the ball.
