Teams generally don't rebound after falling from the winners' bracket to the losers' bracket.
In an eight-team tournament set up like the College World Series (or Women's College World Series), the terms "winners' bracket" and "losers' bracket" really only refer to a couple of games.
There's only one "winners' bracket" game on each side of the draw each year, pitting two 1-0 teams against each other. The rest of the games, after the opener, are either losers' bracket games — elimination games, really — or games in which at least one team can be eliminated.
And dropping to the losers' bracket from the winners' bracket is easy: Two teams do it every year, and Florida did it on Monday by sputtering at the plate in a 1-0 loss to Virginia.
