I find this dynamic interesting between team and individual sports.
Team:
Golden State is bad for basketball because they're too dominant.
UConn women are bad for basketball because they're too dominant.
Alabama is bad for football because they're too dominant.
(To a lesser extent this is heard) The Patriots are bad for football because they're too dominant.
Yet, in individual sports:
In men's tennis, the Big Four are worshiped. I'm not sure if they've ever all been together in the same semi-final, but whenever they meet in a final it's always billed as another all-timer. Especially when Federer went on his run, there was no talk of tennis being boring.
Serena Williams is women's tennis.
Jimmie Johnson won six straight NASCAR titles, and not only was it not bad for NASCAR, he would never even be considered the most popular driver during that stretch.
Don't pay too much attention to F1, but it doesn't appear that Lewis Hamilton winning every week by 30 seconds is ruining that sport.
And then you have Tiger Woods and golf. Guy mowed down competition for 15 years and throws it all away with addiction and infidelity. What happens in the interim between his downfall and his return? Despite the playing field being blown wide open, where you can, for the first time since the mid 90s, expect someone other than the guy wearing red on Sunday to win, golf is considered ruined.
