Ever heard of the idea of quality over quantity?
I don't think there are necessarily too many fight cards, but I love basketball too, for example, and an 82 game season is definitely overdoing it. I'd rather have something along the lines of a 66 game season and have fewer players with nagging injuries come playoff time.
As for the UFC, there are about 3 cards in that list that I really wouldn't have missed if they weren't put together.
Well put, I completely agree.
