At some point the results are just who you are.
I agree and WSU is overachieving where UW is doing what the richest school in the North should be doing.
Now if you put Leach at other schools. Same tenure. Do you think he does better? If Leach was given the resources of UW/UCLA/USC does he do better?
Now if you put Petersen with the resources of Oregon State / WSU does he do the same or worse? Same tenure.
I think that’s an easy question to answer. Given the financial and recruiting advantages of UW they give Petersen an edge that others don’t have.
Where as Leach’s coaching creates its own advantage.
