I know probs my less about golf than any e on here.   I have spent a lot of time at the driving ranges having fun, and played maybe 54 total holes in my life.  Most of those I can't remember due to alcohol consumption.   
But Tiger woods has brought a sport that was an afterthought to most folks, and made it into a common discussion poiny.  He was a badly needed infusion of youth and qe11.  
He brought new players, new dollars, and a new energy to the game. 
Anyone that doesn't think he was good for the sport is just plain wrong.
