The Superbowl is a week from now. I'm not a big fan of football, because of the huge wait in between games. I'd rather watch hockey, baseball or basketball, where the teams play multiple times a week, not just once a week.
Both teams get a week-long break before the Superbowl, which seems like too much for me. I'd improve the football playoffs by making them like the other sports, with each round of the playoffs being a "best 4 out of 7" competition. Football's current "best 1 out of 1" setup is kind of harsh. I'm sure there are many teams who lost the playoffs, just because they had one bad game.
It takes three wins, to win the football playoffs. In the other sports, three wins doesn't get you out of Round One of the playoffs.
There's also the problem that most of a football game is timeouts and waiting for people to get into position. Why do they run the clock, when players are getting into position? You should run the clock when they are actually playing football. Also, I have a hard time getting into the game, since the TV networks run commercial breaks after every single play. Sorry, but it's hard to focus on a sport if they take three minute breaks every half-minute.
