Jags would likely be the team they need to catch unless the Chargers tail off badly...
Jags have Colts twice still and also the Broncos on their schedule. Other games are pretty cake but Titans play tough usually and they have them twice as well still. Division games are usually not cakewalks even if they are better than the other team.
Have the Jets and Cards as well, so those should be Ws, but Jags are weird.
Chargers still have it rough tho with Eagles, Chiefs, Broncos and Texans on their schedule.
So they definitely have a punchers chance of catching both the Chargers and Jags.
Not sure how 3 way tiebreaker would fall but Chiefs best bet would maybe to get into a 3 way tiebreaker with Chargers and Jags if they can't pass either of them. They already lose the tie breaker to the Jags since they lost to them earlier. Currently losing that to the Chargers as well since they lost to them week 2 but have a chance to even the record.
