I do mean the 21st Century, because a lot has changed since then. Ross is a good example, and he’s the last one I could think of they doesn’t fit one of the aforementioned descriptions.
Gailey’s career record is mostly mediocre, so he falls under #2. We got exactly what you’d expect out of him, given his track record.
Johnson is nontraditional, and fits #3 perfectly.
Collins is #1, although you could make an argument for #2 if you think 2 mediocre years at Temple count as “experienced.”
Even in basketball, our last two coaching searches have resulted in other schools saying “good riddance” after we hired their coach away.
