No, there's no excuse for it. But you can't fire a guy (or make the decision that he's going to be Wade Houston 2.0) every time he loses a game that he has no excuse to lose. You would've fired Nick Saban after his first season at Alabama, and you would've fired Bruce Pearl in his sixth season at Tennessee (despite his first five seasons screaming that he was an actually good coach).
Right now, I'm just hoping the stretches of good play keep getting longer, and maybe by Cuonzo's 2nd or 3rd year the whole game looks like that. Because if our whole games looked like the stretches of good play, we'd be somewhere between 7-2 and 9-0 right now.
Another thing that has me wanting to refrain from passing too complete of judgement early is that his first Missouri State team also took a big hit from the previous year (they had gone 8-10 in conference the year before, went 3-15 in Cuonzo's first year) but he pulled them back out the next two years (up to 15-3 his last year)
