Yup... its just tough to say Quin should do that when the roster says that is impossible (maybe).
I get that. Can you turn Bojan into a rangey defender who is at defend 2v3 situations on the weakside? Probably not, and he's not the only one on this roster. We are playing with so many statues on defense and you can't put that all on Quin. But I do think defense is very habitual, and Quin built habits for everyone besides the C to be a statue.
If he doesn't recognize that he's part of the problem we are done for. It's frustrating to see everyone asked to do less on defense when that is clearly our main issue. One of the more disappointing things over the past few seasons is how we've essentially allowed Mitchell to become a complete zero on defense and embrace his new found awful defense. Meanwhile, Monty Williams has Devin Booker taking on the toughest assignments and fairing well in those matchups. Demand more from your players, not less.
I can't disagree if you think Quin had an impossible task defensively with this roster. But I also think his coaching his very much a part of the problem. Give him 5 all NBA defenders and we still get cooked with our defensive principles.
