The Buffalo Bills, one could say, are embarking on perhaps their biggest playoff run in recent memory.
With the failed attempts of previous seasons weighing heavily, the time is now for Josh Allen to break through and deliver that elusive Super Bowl.
But there are reasons why the Bills might not be able to make it to the Super Bowl, and it has nothing to do with Allen and the offense.
For CBS Sports' Zachary Pereles, Buffalo's biggest weakness entering the playoffs is its run defense.
"It's a tough call between run defense and outside wide receivers as Buffalo's biggest weakness, but ultimately the run defense is too big an issue to ignore," Pereles writes. "Only one team ever -- the 2006 Indianapolis Colts -- allowed more than 5 yards per rush and won the Super Bowl. The Bills were at 5.1.
"Plus, when it breaks, it breaks completely: Buffalo allowed eight touchdown runs of 30+ yards, most in a season in NFL history."

Is Bills' run defense that bad?
After 17 regular-season games, it is easy to make the case that yes, it is.
Buffalo allowed 136.2 rushing yards per game (ranks 28th). That isn't good.
But over the last six regular-season games, the Bills only allowed 100+ yards twice. But that's not the entire story.
The two times they did, they surrendered 246 rushing yards and 160 yards. So to Pereles' point, when the dam wall breaks, there's no stopping it. Just six times this season, Buffalo has kept a team under 100 rushing yards, and two of them have come in their last two games.
So, the plan seems rather straightforward for Buffalo's opponents -- run the ball.
