Now that I think of it, there were some teams I "liked" growing up but I wouldn't put them in the "2nd team" category...
I remember really being into the Bears in '85. I was always a huge Walter Payton fan, and almost every kid in the planet wanted to be Jim McMahon that year.
I remember kind of being into the Jets. The years with Richard Todd, Freeman McNeil, Lam Jones, Wesley Walker, Mickey Shuler, and the New York Sack exchange. Joe Klecko was actually from my area, his brother still runs a landscaping business around here as far as I know. Plus they were green like the Eagles and had a similar chant, so I always felt a connection.
I loved watching the NBC 4 o'clock ET games when I was a kid, and usually the Chargers were on. Where I was it was cold and dark already, but I turn that game on and the sun's out, everybody is in t-shirts, and the Chargers are just pitching the ball around like it's 2011. Loved watching Dan Fouts and Kelen Winslow. Wes Chandler always looked like the fastest guy on the field, and Charlie Joiner was always the "old receiver" who was productive in spite of his age.
