What could go wrong? Lions defense among the 6 most-flawed units in playoffs

With the 2024 regular season wrapped up, 14 NFL teams remain in contention for the Super Bowl. 

Only one team will emerge unscathed, of course. The other 13 will most likely fall victim to their flaws. 

FOX Sports has identified the most "questionable" units (offense, defense, special teams) of all of this year’s playoff teams, which could hold their respective teams back from a deep playoff run. 

Here's our top six: 

Houston Texans offense

Offense is the reason why most expect Houston to be one-and-done in the playoffs. 

Quarterback C.J. Stroud has struggled — a step back from his historic rookie season — but the surrounding circumstances have been unfavorable, too. The offensive line has been a liability in both the run and pass game. Offensive coordinator Bobby Slowik’s game management and playcalling have drawn scrutiny, raising questions about his future in Houston. On top of that, the Texans don’t have two of their top three receivers, with both Stefon Diggs and Tank Dell out for the season with torn ACLs. 

The team ranked below average in most offensive metrics during the regular season — scoring (19th), total offense (22nd), total touchdowns (35), EPA per play (20th) and pressure rate allowed (28th), among them. 

Pittsburgh Steelers offense 

Quarterback Russell Wilson and Pittsburgh’s offense went into a downward spiral over the last month of the season, and it’s hard to see how that suddenly changes for the playoffs. The Steelers scored fewer than 20 points in each of their four straight losses to end the regular season, a span in which they had six turnovers. Wilson’s passer rating fell in each of those games too. 

Outside of receiver George Pickens, the Steelers don’t have a true threat on the outside
