The revenge motive in the NFL, factor or not?
That depends on which side a team fell on the initial outcome.
For the Steelers, in preparation for their wild-card game against the Dolphins last week, it worked to remind them how they were handled at Miami during the regular season.
Pittsburgh walloped the Dolphins 30-12.
Now, it's the Chiefs' turn to think about payback with the Steelers visiting Arrowhead Stadium for an AFC divisional round game Sunday.
In the fourth game of the regular season, the Chiefs played a prime-time game at Heinz Field. Actually, the Steelers played. The Chiefs barely showed up in a 43-14 loss that wasn't as close as the score suggests.
The Steelers led 22-0 after the first quarter, 29-0 at halftime and 36-0 before the Chiefs scored.
"It was embarrassing," Chiefs center Mitch Morse said. "There's a little chip on our shoulders. It left a bad taste in our mouths."
Phooey, said Steelers quarterback Ben Roethlisberger.
"I'll be honest, I didn't really think it was much motivation," Roethlisberger said. "You're in the playoffs. If you need a revenge factor in the playoffs to help you win something's wrong with you. We didn't even think we beat (the Dolphins) because they beat us earlier.
