The NFC East leads the league in hype. The huge media markets in which the teams play, the history of success, the rivalries ... all of it combines to create a perception that the NFC East is the best, most competitive and toughest division in the NFL. That the defending Super Bowl champion New York Giants play in it -- and are not the clear-cut favorites to win it again this season -- only adds to the perception, as does the growing excitement over an NFL regular-season opener between the Giants and the Dallas Cowboys 16 nights from tonight.

But while Giants-Cowboys is fun, and each of those teams has something pretty intense going with the division's other two teams -- the Giants' recent struggles with the Philadelphia Eagles and the Cowboys' longstanding rivalry with the Washington Redskins -- the stats don't back up the NFC East as the league's toughest division anymore. The division is, by many measures, coming off its worst season ever. Last season was the first regular season in NFC East history in which no team won at least 10 games. Only the Giants finished over .500, and they gave up more points than they scored. Their Super Bowl run might have saved the division's honor, but it also disguised the troubling fact that the NFC East is no longer the Beast it used to be.

A large part of the reason for this, I believe, is the state of the division's offensive lines. We all know offensive line play is important, but in the NFC East these days, concern about the lines affects too many things. Teams that are strong on the line can control games. Teams that aren't cannot. Eli Manning and the Giants have been talking for months about wanting to not have to come back in the fourth quarter as much as they did last season, and the best way to avoid that is to control games from the start. Given the issues with their offensive line, they could find that a challenge once again.

But they're not alone. As we look ahead to 2012 and start assessing everyone's biggest questions, offensive line stands out as an issue for each of the NFC East's four teams. To wit:

Giants left tackle Will Beatty is unproven and can't get healthy, and they're thin at tackle in general. Additionally, David Baas was a disappointment in his first season in New York, and they haven't seen Kevin Boothe as a full-season starter yet. The Giants finished 32nd in the league last season in rushing offense because of a line that couldn't get any push. Pro Football Focus graded them the 29th-best run-blocking team in the league, and the worst pass-blocking team in the league. Good for them for overcoming it all and winning the Super Bowl, but it remains an issue insufficiently addressed.

The Cowboys' offensive line has been the dominant story of their training camp -- specifically their struggles at center, where Phil Costa has been banged up and the potential backups and replacements for him have had trouble snapping the ball to the quarterback. The Cowboys also are trying to find guards who can protect Tony Romo against the interior pass rush better than they did last season. And starting tackles Tyron Smith and Doug Free have had to switch sides because of Free's struggles on the left last season. PFF had Dallas as the 15th-best pass-blocking team in 2011 and the 11th-best run blocking one, so it could be worse. But they need everyone healthy and playing together to see if they have a chance.

The Redskins likely were planning to use some of the $18 million in salary cap money the league took from them on the eve of free agency to upgrade the offensive line. But they couldn't, obviously, so they're still dealing with Jammal Brown's hip injury, Kory Lichtensteiger's knee injury and Will Montgomery's limitations as a center in their zone-blocking run scheme. The Redskins ranked 26th in pass blocking and 30th in run blocking last season according to those PFF grades, and they also made no significant change or improvement.

After a rocky start, the Eagles had a good season on the line in 2011. They ranked second in the league in run-blocking and 14th in pass-blocking. But they also lost left tackle Jason Peters, their best lineman and one of the best in the league, to an Achilles injury in the offseason. As good as the other four starters on their line are, the Eagles could struggle to replace what Peters gave them last season, and so far they have not figured out whether Demetress Bell or King Dunlap replaces him as the starter.

The NFC has no shortage of star power. It has three great quarterbacks and one, Washington rookie Robert Griffin III, who's getting as much hype as any of the other three these days. It has some of the great wide receivers in the league in veterans such as Hakeem Nicks, Miles Austin and DeSean Jackson as well as rising stars such as Victor Cruz, Dez Bryant and Jeremy Maclin. The Eagles' LeSean McCoy ranks with the game's great running backs. And on defense, of course, the division is known for its great pass-rushers. Each team can rattle off names that give opposing quarterbacks heartburn. DeMarcus Ware. Jason Pierre-Paul. Justin Tuck. Trent Cole. Jason Babin. Brian Orakpo.

All of that makes the NFC East very exciting. But very often in the NFL, excitement and hype can conceal issues of quality. And if the NFC East really wants to be the best division in football again, it's not the quarterbacks or the wide receivers or even the pass-rushers that will bring it there. The NFC East's teams all need to start paying more attention to their offensive lines, because as those continue to erode, so will the division's annual claim to Beastliness.
