Tiger has way too much talent too never win another major. Afterall he won a major with a flawed swing and playing on 1 leg.
Once the cluster f*** life that he created settles in so will his golf game. He needs to settle on a coach and a physical fitness regiment that will reduce some of the musculature that he developed over the years, or he has to have a swing suitable to his new body type. Plus he's 32 years old now, so change does not happen as easily as it once did.
Whatever my 2 cents worth.
