You gotta understand folks in ATL... short attention spans, so if the team is losing, they're leaving. "Hey, I still got a 6-pack in the truck...."
I lived there for three years, saw the Braves turn it around. There was all sorts of headshaking and hand-wringing over the release of Dale Murphy, their beloved son. But when the team started winning, then any trade or managerial action that benched a loyal and good player was justified. Ron Gant was an integral part of that early success (back-to-back 30/30 seasons), and caught the first septic truck outta town after breaking a leg in the OFF-season.
It's pretty much normal for pro sports fans these days; how many Laker fans hate Shaq now?
