Andrew,
Proof is in the numbers: 5.0, 14 rating for the final round of The Open, biggest since 2000 - same guy, same place. I'll wager the Senior British doesn't garner half that.
Present PGA TOUR contract ('02-06): almost 900 million, 45% more than the previous four-year deal. All thanks to you-know-who.
Ratings go up 65% when Eldrick is playing. More when he is in contention.
Loved Norman, brought a lot to the game, can't deny his being number one for four or so years. But he never, ever, ever had that kind of impact.
