I watch because its my team. When the Jets were 3-12 in 1995 I went and set in the upper deck freezing my balls off to see us go 3-13. Then came Keyshawn, then came 1-15 and then came Peyton Manning staying in school and us trading down. Most years are like that. But eventually things fall your way and you get '98 and a conference title game in Denver, and then '09-'10 and back to back title games. Eventually, maybe, perhaps, in my lifetime we'll win the big one.
Have to stick with your team because things will turn around.
