Depends who is playing. If I have the top two hockey teams or two average football teams I'll watch the NHL, but if it's the top level of every sport I'll take a great tennis match. Football would be my next choice though.
Give me Fed - Nadal type finals like the one we just saw, I'll say tennis.
But, if you give me the Red Wing 4 ot type Stanley Cup games like the one we just saw, I'll say hockey.
Give me Giant - Pat type Super Bowl................
What am I saying?
Give me a good game, I'll watch anything.
