I remember the Denver Broncos had the longest sellout streak before Invesco was built. I wonder if they are still selling out Invesco. Denver fans are some of the best.
I would say the Cubs, but you threw in that little thing about playoffs. I would guess Portland or the Bulls since they both had about 10+ years of selling out.
Hard to believe about the tennis. They must be very well schooled with the media because they all sound very intelligent.
