It was one of the best finishes to a play-off game in NFL history.Two years ago, the Kansas City Chiefs had a narrow lead in their divisional round game at home to the Buffalo Bills. Then Patrick Mahomes and Josh Allen produced a quarterback masterclass.

In the final two minutes, the lead changed hands three times before the Chiefs kicked a field goal to force overtime, in which they clinched a 42-36 win on the first possession.

For Mahomes and Allen, the two young stars, it was a match to suggest the beginnings of a classic rivalry.Mahomes hinted as much afterwards, when he said: “We’re going to play this team [the Bills] a lot in games like this. With that quarterback [Allen], that coaching staff and those players, there are going to be a lot of battles.”

The next such battle takes place this Sunday, again in the divisional round, with Buffalo hosting the defending champions for the latest chapter in a quarterback contest that could come to rank among the all-time greats.

And there is plenty more drama in store this weekend as the top seeds join the play-off party having earned a first-round bye, with three in-form underdogs aiming to pull off an upset.
