Could Sam Presti be making his "3rd Strike" decision with Donovan?

With reports that Oklahoma City is in "serious talks" with Flordia's Billy Donovan to become the next head coach of the Thunder, one has to wonder, is Sam Presti making his 3rd big mistake as the team's GM? 

Mistake 1 was letting James Harden go to Houston. If OKC keeps him, I think last and this year's results are different. 

Mistake 2 was Kendrick Perkins' ridiculous contract that kept him on the team WAY past his productive prime. Presti got lucky in being able to trade him off to Utah this year in the big 3 team trade that brought Enes Kanter and others to OKC. 

Colleges coaches with no previous NBA experience don't have the best track record, so why would Presti hire a guy like that when there are better options out there? 

Time will tell if this makes Presti look like a genius or sends him looking for another job. But of course, these are really just my random thoughts.
