Tiger Woods IS a more dominant athlete at this point. Though it's really hard to quantify in terms of numbers. I don't think it's a one to one correspondence with majors to superbowls. BUT... Where Tiger is at this point in his career vs. where Brady is. And the distance between him and the next nearest competitor.
Sorry, I don't think it's even close. Tiger is redefining his sport. He is demolishing records from careers 2-3x as long as his. It would take several seasons as good as this one for Tom to be even considered near par with Tiger, I think.
I hate to even debate this because I think Tom Brady is, without any doubt, the single greatest quarterback ever. But I just think that tells you how great i think Tiger is in his sport. I mean absolutely no disrespect to either athlete.
As a sports fan, I am so grateful to have the chance to see them play in their primes. It truly is a great time to be a fan.
