A lot of that has to do with the fact that they can show their butts with no repercussions. They think that because they are coaches, they not only know more about football than me, but they know the rules better as well. We all make mistakes and most of us learn from it.
I look at it this way anymore. I will be at a football game every Friday night regardless, so why not get some extra money instead of paying to get in? The money is not much, but without us there doing our job, these teenagers can't do the same thing that 95% of us did in high school, enjoying the game we love.
