Everything changed Wednesday morning when the veteran guard elected to retire.
"We had conversations with him and we thought he might come in and help our team out," Garrett said Wednesday. "The conversations were way down the road and we thought we were close to an agreement with him, and he decided when he awoke up this morning he didn't want to play football anymore. So we respect that decision. We'll continue to try and evaluate that position as we go forward."
The Cowboys wanted to sign Moore to become a potential starter along the interior of an offensive line that is battling injuries. Projected starting left guard Nate Livings will miss maybe three weeks as he recovers from knee surgery. Guards Ray Dominguez (shoulder) and Kevin Kowalski (knee) are also nursing injuries.
"Brian Waters has been a really good player in this league for a long time," Garrett said. "As you guys know, I think he's a six-time Pro Bowler. He's an NFL Man of the Year, played a long time in Kansas City a few years ago, he came late to New England and had a Pro Bowl year for them when they went to the Super Bowl. The biggest issue for Brian right now is he hasn't played in 18 months. You have to factor those things in."
