Who Is the Best Team in the NFL, Clemson vs. Notre Dame, Harbaugh Overrated?

The homie Duane Nash and I will be debating who is the best team in the NFL (Chiefs, Steelers, Buccaneers?), previewing Clemson vs. Notre Dame and is Jim Harbaugh overrated or not? My Pittsburgh Steelers are STILL undefeated, but the Kansas City Chiefs are still playing well as the defending champs, and the Tampa Bay Buccaneers and Seattle Seahawks are straight balling. This debate of who is the best team in the NFL will be settled once and for all (until next week).Clemson at Notre Dame is by far college football's "Game of the Year". Does a Clemson win with a backup QB make the Tigers the team to beat in all of college football?I've long contended that U. of Michigan head football coach Jim Harbaugh is overrated as hell. Hopefully I can FINALLY convince D-Nash the same.
