KANSAS CITY, Mo. (AP) — The Chiefs had to learn to dink and dunk their way through this entire season so you can bet they relished the chance to open up the offense against Pittsburgh on Sunday night. The Chiefs used a series of big plays to roll to a 42-21 victory in the wild-card round. They'll probably need more of the same this Sunday night when they face the equally potent Bills in the divisional round at Arrowhead Stadium. It's a rematch of last season's AFC title game won by the Chiefs and an October matchup in Kansas City that the Bills won in a 38-20 rout.
