If you can't see the difference between a Program's overall history and a coach's recent W-L record, then I don't think there's much more of a basis for us to discuss. To use UT Football as the example, enduring the Mackovic years did not take away from the fact that UT was a tradition-rich program. Going 4-7 and losing to UCLA by the score of 66-3 gets Mackovic, as the coach, canned even though he won the Conference the year before and went to the Fiesta. And nobody had a problem with him getting fired.
But, UNLV's history was never the point, anyway. I do not consider Kruger to be a particular winner based on a thoroughly average track record. 9 years and two jobs are, in my opinion, a very reasonable period of time to measure one's track record of success or lack thereof.
I'm not trying to be a jerk and picking an argument. You're free be a fan of Kruger or whomever. But these discussions are supposed to be for, well, discussion.
