I wouldn't rule out anything in sports, but I would think that if nothing turned up for him this summer, he could come back for a season or two until another good fit for him opened up.
Do you think that Dunlap's style was more disagreeable to Jordan than the actual win output?
It's gotta be something like that, the players were rumored to be complaining about his disciplinary style from early in the season as I recall. Can't imagine anyone expected better results with that roster.
