I actually think Tiger's epic fall from grace is good for golf and America.
It teaches kids 3 great lessons:
No matter how good you get, you can still suck someday, so be humble and treat people with respect on the way up.
Do steroids and your body will break down.
Treat people like crap and you will be unhappy in life.
I Also see no downside:
Who really cares if pro golfers make less money? Or any pro athletes for that matter?
