I used to think, that this is one part of a possible explanation for the Cuz+KK lineups. The other part would be potential foul trouble as the lone big, who needs to defend the rim.
But that's not what Joerger said in this interview. He very openly declared, that he likes Cuz as the PF, because he thinks nobody can guard him at PF.
And that's not something I'm buying. In a Cuz+KK pairing Cousins is usually defended by the best defender out there. Some teams defend him with a big man. Some teams opt for a smaller, quicker guy harassing him on his drives. But all teams hide the defensively weaker part of their front court on KK. KK isn't a guy, who can abuse people on the offensive end. So where is the offensive benefit of the KK+Cuz lineup? On the glass? Kosta grabs 1.6 ORB this year, so it's save to say, that he isn't pounding the opposition on the glass.
Ultimately Joergers preferation of DMC at PF only makes sense, when we would be able to pair him with another big able to power through weaker defenders. That would be the Grizzlies blueprint of 2 years ago. And barring a Willie explosion, who can guard the perimeter much more effectively than DMC, I'm certainly not convinced, that this is a promising vision for this team.
