From Bill Barnwell's story featuring eight surprising wild-card weekend facts: "If you were going around the league and ranking each team's respective set of wide receivers, Pittsburgh wouldn't be far from the top. Antonio Brown is Antonio Brown, and the strides made by Martavis Bryant and Markus Wheaton this season leave Ben Roethlisberger's trio of weapons as one of the league's most dangerous combinations. Nobody in football has a great fourth wide receiver, and the Steelers are no exception to that rule. Darrius Heyward-Bey is a known quantity at this point, combining speed with all-too-frequent drops. Based on an admittedly small sample, though, the Steelers might want to get DHB onto the field for a few extra snaps this weekend."

From Field Yates' story on the 20 most important players in the playoffsInsider and why Packers quarterback Aaron Rodgers is No. 1: "Has Rodgers played better than every other quarterback in the NFL this season? No. But Rodgers at his best is a quarterback who can carry a team to victory on any given Sunday, even with a roster that has underwhelmed offensively due to injuries and difficult-to-explain performances. Green Bay doesn't feel like a strong contender for the Super Bowl after finishing the season 4-6 (and nearly 3-7, save a miracle Hail Mary against Detroit in Week 13), but the NFL presses reset at the start of the playoffs, and if the Packers are going to make a move, it will be on the strength of Rodgers' brilliance."

From ESPN Stats & Information research: Kansas City's last playoff win came in the 1993 divisional round (Jan. 16, 1994) when the Chiefs defeated the Oilers at the Houston Astrodome. The Chiefs are 5-9 in road playoff games, but 2-0 in Houston. Their first-ever playoff win also came in the city when the franchise was known as the Dallas Texans.
