Donovan will be giving up more assist and points than he will be accruing them if he has to play defense next to Kennard.
Thus the conundrum of building around someone as limited as Donovan.
Oh we need good defenders next to Don so he wont be exposed by dudes like Jalen Brunson. You got to put Don on the absolute worst perimeter player who is no threat to create.
Oh they also got to be able to shoot cuz you want to play 5 out cuz the only passes Donovan can make are drive and kick.
So the Jazz got to get a bunch of really good defenders who are long and big, and they also got to shoot.
Oh I forgot, Donovan also isnt good enough to be a mega usage star like a Doncic/Harden, so you need another player with high level creation ability, but that guy can't be short and he has to be able to guard so we can stick Donovan on nobodies.
It just doesnt work.
*and yes, before the weasels respond, Gobert is also very difficult to build around, but less so IMO*
