The Titans certainly have a chance. Patriots fans can look back at the 2010 season and see anything can happen in the NFL Playoffs. In 2010, the Patriots beat the Jets on MNF 45-3 at Gillette and a month later that same Jets team came to Foxboro and beat the Patriots 28-21 in the Divisional Round. Tom Brady was the unanimous MVP that season too. 

The Jets won that game forcing Brady to turn the ball over and flooding the zones where Brady's favorite WRs were expected to be.

Mariota can play mistake free football. His threat to run also will stress the Patriots front 7. My guess is Bill will try to take away Henry and put the ball in Mariota's hands. 

Going into KC and winning is a tough task. The Titans were able to pull that off, so why can't they do the same in Foxboro?

On the Patriots side, Brady has to be happy getting Chris Hogan, James White and Rex Burkhead back. A week off to rest and gameplan should help. The Patriots secondary has to continue to improve and the front 7 needs to limit big running plays. Seeing a potential 6th Super Bowl Championship at the end of the tunnel is all the motivation this team should need. We shall see. 

I think this game will be closer than people think.
