9. Tiger Woods, 2001
Five PGA Tour wins, including the Masters, would be a career year for anybody -- anybody but Tiger. For folks with short memories of just how dominant Tiger was, year-after-year, 2001 was only Woods' seventh best season in his pro career. Yet, he won Arnie's event at Bay Hill, Jack's party at The Memorial and The Players, among others. 18 top-25s in 19 events, one other European Tour win -- amazing, but routine for Tiger.
