Tiger Woods, Thanksgiving 2009 to present
To be fair, Woods had plenty of critics before he crashed his Cadillac SUV into a tree and a fire hydrant in the early morning hours the day after Thanksgiving. But the ensuing avalanche of rotten news, that Woods was cheating on his wife, Elin, and the parade of publicity-loving mistresses pretty much sealed his fate as golf's villain of the moment. Can his image recover? We'll have to wait and see, but time and victories have a way of curing all. Just ask Kobe Bryant.
