Would they be able to make it work together on the floor?
I see no reason why not. They play different games and you can rotate them to have each of them play 32mins per game. Jokić is finesse, cerebral, great passer, soft touch, can play 4. Jusuf is brute force but still has a soft touch, good passing game, can protect the rim, good movement etc.
In either case, trading him for Plumlee and then playing Plumlee 6mins more than you played Jusuf was idiotic back then and it looks even worse now when he established himself as a really good player in the NBA. I mean the stat line he just posted has never been posted in the NBA, 20+ points, 20+ boards, 7 assists, 5 steals, 5 blocks. Those are video game numbers.
They weren't. And Nurkic pouted about not getting enough touches.
Nuggets never made a consistent effort in trying to get those two on the court on a consistent basis. And he pouted with good reason, not for not getting enough touches, but because he wasn't being used enough. He played little over 17mins per game, same as guys like Hickson, 8mins less than Faried, less than stalwarts such as Laverngue and Arthur etc.
