Floor is failure, and degrees of really bad don't really matter, floors is a dumb discussion for a coach anyway, what you really want to gauge is... Expected median outcome and reasonable ceiling, because any guy who ends up at his flooring is getting fired in 2 years anyway.
Now I think you can make a case that Vrabel has the higher expectedly median outcome, in fact I said that earlier in the thread, and it's a good argument for him... But I push back on the argument that he has a high floor because people use it incorrectly to say that "well at least there isn't a chance it's really bad".. Because there is a chance, in fact a good one that it will be really bad for both coaches, the roster is garbage, the operation is outdated, the ownership is suspect... The most likely outcome is is that it is bad... Maybe really bad.
