A quick couple thoughts...
1)Tiger had a big Rc. push in the collectable market, but it really fizzled quickly(Compared to say Pujols, or Lebron)
Then a few spikes like his crushing the field headlines...one being the "Tiger Slam" which was golden
2) When all is said, and done, Tiger will have(sounds funny..lol) created many "I gotta have a Tiger collectable" like the latest Masters. Where in other sports it's usually a season long achievment, or a record book assault that gets attention.
Also, He appeals to such a large consumer/fan base, heck my girls know who he is. IDK..Maybe it's the optomist in me. plus, there's only 1 legit product!? maybe 2.
Kindof a ramble..House full o' people
