Breakfast links: So long, Jaiquawn Jarrett

Happy Wednesday. Let's get you caught up on some of the transaction and other news that went down late in the day Tuesday with a heaping helping of your morning links.

Dallas Cowboys

While much of the talk about DeMarco Murray has been about his tough running and his somewhat disconcerting love of contact, Todd Archer writes that it's important to take note of the second-year Cowboys running back's football intelligence, too. Murray is a big key to this offense -- a fearless running back who, like quarterback Tony Romo, can help the Cowboys succeed in spite of their offensive line issues. They need to keep him healthy.

Jerry Jones remembers that the Redskins nearly beat the Cowboys twice last season when Washington's quarterbacks were Rex Grossman and John Beck. And after watching Robert Griffin III's debut Sunday, Jones says he's not looking forward to seeing the Redskins this year or in the years to come.

Washington Redskins

Mike Shanahan says that, when considering the kinds of run plays they wanted to design for Griffin, the Redskins' coaching staff watched tapes not only of Griffin's college games but also 2011 tapes of running quarterbacks Cam Newton of Carolina and Tim Tebow of Denver.

The Redskins have placed long-snapper Nick Sundberg, who played the second half of Sunday's game with a broken left arm, on injured reserve/designated to return. That's the new IR, that doesn't require the player to sit out the season. Sundberg must miss at least eight games. His replacement is former Colts long-snapper Justin Snow.

Philadelphia Eagles

You are now free to call 2011 second-round pick Jaiquawn Jarrett a bust if you so choose. Despite opportunities to contribute at safety during his time in Philadelphia, Jarrett failed to show much of anything, and he was cut Tuesday so that the team might bring back wide receiver Mardy Gilyard. Thin at receiver due to injuries to Jeremy Maclin, Jason Avant and Riley Cooper, the Eagles decided it was more important to have an option at wide receiver this week than it was to maintain whatever depth Jarrett might represent at safety. A missed special-teams tackle in Sunday's game may have been the last straw for Jarrett.

Eagles wide receiver DeSean Jackson donated $50,000 to the Wounded Warrior Project and spent the 11th anniversary of the Sept. 11 attacks hanging out with some of the soldiers the organization works to help. Good work, DeSean.

New York Giants

Left tackle Will Beatty is hoping he gets cleared to start and play Sunday against the Buccaneers. He says he's ready to go because he's been working against the Giants' excellent defensive ends in practice. But he wasn't OK to start the season opener, at least not according to the team, and so he waits to find out.

Victor Cruz says he knows he's a marked man after his breakout 2011 season. And he understands he had a bad game in the season opener on Wednesday. But it's about looking forward, and Cruz and the Giants insist they're better prepared this week.
