re: The most irrelevant team in the NFL is?

My vote is the Titans.

Cleveland has only been relevant simply for how big of a dumpster fire its been under the Haslam regime.

To me irrelevance means it doesn't matter what a team does nobody really cares nor does it matter. The Titans could be a playoff team and are 4-4, the only thing that mattered was the Cowboys losing to most people. You also cannot take any Oilers history as part of their franchise so since 1997 they actually have been to a super bowl but most forget it about.
