STEELERS (3) AT CHIEFS (2)

When: Sunday, 1:05 p.m. ET (NBC) Where: Arrowhead Stadium, Kansas City, Mo. Line: TBA

THREE THINGS TO KNOW

1. Home cooking? As intimidating as Arrowhead Stadium can be, the Chiefs have lost their last four home playoff games and haven’t won in front of their faithful fans in the postseason since the 1993 season. But it’s hard to believe they won’t have a significant advantage. A Pittsburgh offense that tends to be far less effective on the road anyway also will have to overcome the ear-splitting din, and a change of venue can only help after the Steelers dismantled the Chiefs 43-14 at Heinz Field in Week 4.

2. Hill’s thrills: A middling Kansas City attack has been augmented lately by rookie WR Tyreek Hill, who has scored a touchdown of at least 68 yards in each of the last four weeks. He is a threat through the air, on jet sweeps and especially on special teams, where he’s scored three times on returns. Pittsburgh must respect Hill’s elite speed, and that will only open up the field for all-pro TE Travis Kelce, WR Jeremy Maclin and the running game, which is augmented by QB Alex Smith’s ability to operate outside the pocket. 3. Pitt’s triplets: Steelers QB Ben Roethlisberger, WR Antonio Brown and RB Le’Veon Bell showed just how dangerous they could be in their first playoff game together. Big Ben found Brown for 50- and 62-yard TD passes in the first quarter of Sunday’s wildcard win against the Miami Dolphins. Bell, making his postseason debut and playing for a new contract, took over from there, adding two scores on the ground along with 174 yards from scrimmage. The trio was even more dominant in the October blowout of the Chiefs, with Roethlisberger passing for 300 yards and five touchdowns (two to Brown) while Bell racked up 178 yards from scrimmage. However, it must be noted that Big Ben has been ordinary, at best, on the road in 2016 (nine TDs, eight interceptions, 59.4% completion rate, 78.4 rating) and now also must overcome an ankle injury suffered against Miami.
