Most of your problems with OKC lie with ownership, not Presti.
The one bad move Presti made was not trading Russ instead of Harden. Would have been a tough pill to swallow at the time but was the right move long term.
As it is, they are doing the right thing and Presti and his scouts clearly have eye for talent. OKC isn't exactly a FA hotbed.
I'll be the first to say the team had under-performed as a whole until 2016, mostly because that move made the team too rigid, and any setback was fatal (outside of the foot fracture - no KD team is competing there). Since he left, idk what others expected, but I expected nothing
until the PG-Clippers trade the org was on the exact treadmill I was expecting, and made for some wack ass yrs as a fan. And if it wasn't for him asking out, the team would still be hoping PG and Russ were gonna break through one of these yrs 
This is accurate.
For sure there were some things out of their control but what's been the number one issue with OKC's teams for the last decade? Lack of shooting. Even this year, that squad was relying on Lu Dort to hit corner threes in the playoffs.
For all the talented players Presti's front office is able to find, they never seem to find shooters.
I swear any time someone with a rep of a shooter drops comes to the Thunder their shooting drops, other than Kmart I think. I'm too lazy to check bball ref but from my spotty memory, that seemed to be the case
but there have definitely been very very few snipers. Every position outside of the stars has been more of an archetype than a player. Square peg in round hole type shyt
he's been replacing Thabo with Thabo for the better part of this decade
People love talking about the 3 MVPs but then wanna put the faillures on the FO. If Harden plays like and MVP they win in 2012. If KD and Russ play like MVPs they win in 16. KD and Russ both missed a playoff run with injuries. The Harden shyt was stupid in retrospect but they kept the train rolling and were in position to win a chip and the players didn't close the deal. KD has shown he is a different cat. The chose to trade Russ and acquired picks for him AND got just as far without him as they had with him.
