Couple of things, the Titans playoff debacle was in 2000. Second, Eddie Newman .... not sure if you're referring to Eddie Robinson (who absolutely sucked...if you get juked by Chad Pennington, hang it up) or Keith Newman (who was actually pretty decent).
I'm not sure why Edwards being benched is any reason to give up on the season - he wasn't the long term answer at QB, so I'm not sure why his benching is a big deal, one way or the other.
