The author of this article thinks this year's NFC East could be among the strongest divisions ever. He breaks down each team then hits some historical highlights of really tough divisions from the past.
On Dallas:

QB Jeff Mroz gets some ink today from Todd Archer in a DMN article (sub. required). With the Cowboys QB roster pretty much set, Mroz has to hope he can land on the practice quad.
But there is hope. Practice squads were expanded from five to eight a year ago, and Mroz could be in for a redshirt-type season if he sticks. Plus, he worked with quarterbacks coach Chris Palmer before the draft.
As a senior, he threw for 2,484 yards with 22 touchdowns and 14 interceptions. That was enough to get him a look from a handful of teams after the draft. Because of his relationship with Palmer, he chose the Cowboys.

Gil Brandt says the supplemental draft is coming up and there are two players who could make a splash.
Draft order is determined by a weighted system that is divided into three groupings. First come the teams that had six or fewer wins last season, followed by non-playoff teams that had more than six wins, followed by the 12 playoff teams.

The paperwork hasn't officially been filed yet for this year's supplemental draft, but there are at least two players who will get a close look from scouts around the league:
* Ahmad Brooks, LB, Virginia: A national defensive player of the year coming out of high school, Brooks had an outstanding 2004 season for the Cavaliers in 2004, but got hurt last year.
* Jason Berryman, DE, Iowa State: At about 240 pounds, he's probably a linebacker in a 3-4 scheme. His Pro Day is already set for June 6 at Iowa State, and we'll have reports on that.
