Great points by everybody, but one thing that has not been mentioned is...the use of the baggie as a regular avatar. I know it will be hard to monitor and there is really no way of making sure people don't do it, but the baggie avatar was specifically for losing a challenge...now people wear them for any reason at all...just look at the Lions forum
Maybe we need to create a new av....maybe something similar to what Treat mentioned, having something to do with the team that beat you (colors or such)...just throwing out ideas.
I really like the pre-defined list of games...but we should be able to add on the fly. A Dallas/GB this year should be worthy (both 9-1 or whatever they were at the time)
