Wrong guy for athlete of the decade... it should have been Federer... he did more for his sport. Shattered more records and more impressive accomplishments, his successive grand slam semi appearances. The only reason Tiger won the honor is because golf is a much more popular game right now. But tennis is coming into a renaissance and may be popular once again.
Tiger may have been the athlete of the year in the next decade... but IMHO not this one.
Doing whatever it takes to win... does not make you a winner.
