Billy's last years were noted in my post earlier. And if frank has a similar stretch he should be gone too. Though I believe technically tubbs resigned. Speaking factually about someone isn't speaking ill of them, doesn't mean you hate them ir think they suck. same goes for frank.
So will you acknowledge that Frank would have at least matched Billy's two good years if Mike stayed? Billy would not have had the services of Wayman Tisdale for three years if he coached 15 years later?
unless frank ran beasley off

stacey king would have been gone early too.
however....this is all relative. other great players on other teams would have been gone as well.
