Bah, there is nothing wrong with fostering a good rivarly. Keeping in mind plays like the ones being discussed in this thread are an excellent way to do that. To me, good rivalries are key to sports. If everyone was all lovey dovey and didn't want any animosity towards their fellow man, football wouldn't be anywhere NEAR as entertaining.
So I say screw not living in the past. Thinking about that sort of stuff pumps me up for future games, and the more intensity revolving around my sports teams the better.
