Of course Dallas should be mentioned as being mentioned as a team in contention for the Super Bowl. The only teams ranked above the Cowboys in the NFC are the 49ers and Eagles. The Cowboys are third. By definition, they are in contention. They beat the Eagles once last year. Take away the pick-6 at the 49ers, and the missed extra point, and the Cowboys would have won. Yes, they didn't win, but if two plays is the only difference, the Cowboys are a contender.
As for the Eagles, they can only really play two DT's at a time. They drafted three DT's in the last 2 yeayrs, and still have Fletcher Cox. I get that some Cowboys fans are scared, but it's way to early to believe the Cowboys can't compete with the Eagles.
The Cowboys got stronger up the middle of their defense with both Dline picks this year, resigning Hankins and resigning Vander Esch while drafting yet another linebacker. They got stronger on the edge of their defense also, and already had one of the best pass rushing teams in the NFL.
The only so-called glaring holes on the team are at Left Guard and place-kicker, and they have a plan for Guard. According to Jerry, they will sign a veteran place-kicker.
