In 2013, no team in the National Football League racked up more sacks than the 60 the Carolina Panthers accrued en route to winning the NFC South.
Last season the Panthers became the first team in NFC South history to win the division in successive seasons, but the team's vaunted pass rush fell way off—all the way to 13th in the NFL.
The Carolina defense is in many ways predicated on that front four's ability to make opposing quarterbacks miserable. And if the Panthers are going to win their division for a third consecutive year, that pass rush is going to have to step it up in 2015.
