As a football fan, I'm still pretty jacked up. Not AS jacked up as I would be getting ready for a Texans game but I really like the NFL playoffs. Of course, being a Cowboys fan too, I've got a team in the dance.
By the time the Super Bowl hits, I'm usually ready for it to be over and as a big Astros fan, I start getting antsy for the baseball season to start.
March Madness does a good job of filling the void of no football or baseball. Not a big basketball guy but I'll follow the locals, Rockets, UH.
Right after the Super Bowl until March Madness I usually try to take a sabbatical from sports, get away from the competitiveness and all that. Kinda recharge the batteries so to speak. A "fan" vacation.
I don't get that football itch again 'til about the first of July or so, depending a lot on how good or bad the baseball season is going, and when I know training camp is right around the corner and my season tickets are about to be shipped.
