I think it depends on what you mean by "back into this thing". Heart may have nothing to do with it, compared to timing.
Denver is 5-1 ... if they go .500 over the final 10 games - that's 10 wins.
KC is 1-4 ... they have 11 games left and if Denver wins only 5 more, KC would need to win 9 of 11 games to "tie" Denver (including a win over Denver at Arrowhead to nullify a sweep if they have identical records).
KC has a tough road in front of them if you are hoping for them to compete for the playoffs, even a wildcard.
