Breakfast links: Busy day under way

Yes, it's roster cut day -- the day on which teams must reduce their rosters to 53 players by 9 p.m. ET. It's a day of cuts and trades and lots of activity, and we'll keep you posted on all of it as best we can here on the NFC East blog. Heck, it's already started with a trade in Dallas. See? Links:

Dallas Cowboys

The Cowboys have acquired offensive lineman Ryan Cook from the Miami Dolphins in exchange for a seventh-round pick. Cook can play center, which is key. He's played tackle and guard as well (he started at left tackle for the Vikings in 2008), but center is the position at which the Cowboys consider themselves the thinnest. My guess is he's being brought in to be a backup, but you never know. If Bill Callahan saw something he really liked, it's not as though there aren't starting Cowboys linemen who could be replaced if they struggle early. Cook was slated to be a backup in Miami and is scheduled to make $1 million this year, so that's why they traded him.

Fifth-round wide receiver Danny Coale and linebacker Adrian Hamilton were among the Cowboys cuts. When the Cowboys picked Coale, some had hoped he'd work his way into that No. 3 wide receiver mix. But he got hurt, and the other guys played well, and it didn't work out for him.

New York Giants

The Giants think left tackle Will Beatty could be ready to start the season opener Wednesday against the Cowboys. I guess that would be good, but are we sure? Beatty wasn't exactly Jonathan Ogden over there last year to begin with, and he's barely practiced because of a back problem he's had since May. So even if he does play, it's hard to say how good the Giants should feel about his chances to perform the way they need him to and get through the whole game.

The NFL changed its injured reserve rule Thursday, which means teams can now designate one player as a short-term IR guy and bring him back after eight weeks if he's healthy. It seems likely that cornerback Terrell Thomas would be that guy for the Giants as they pare down their roster tonight.

Philadelphia Eagles

Eagles owner Jeffrey Lurie said another 8-8 record would not be good enough for Andy Reid to return as coach in 2013. People are going to hold Lurie to that, though obviously his hope and that of Eagles fans is that they will not have to. Reid has finished better than 8-8 in nine of his 13 seasons as Eagles head coach.

Trent Edwards will learn today whether he's done enough in preseason to beat out Mike Kafka for the lone backup quarterback spot in question. If it's to be based on preseason performance, there's little question he has. But how much of a break do they give Kafka for the injury that kept him from participating in a competition no one even expected to happen?

Washington Redskins

Wide receiver is one of the places at which the Redskins have some tough decisions to make tonight. Guys like Anthony Armstrong, Dezmon Briscoe and Brandon Banks are very much on the bubble.

I do expect the Redskins to keep all four of the running backs who are candidates to start the Sept. 9 season opener in New Orleans because... well, they're all candidates to start the season opener in New Orleans. The Redskins like all four backs, and each comes with question marks, and right now the best plan is to keep all four for depth and see what shakes out.
