The sides had been dancing around a deal since late July, but it soon became evident that Waters, 36, wanted no part of training camp. Now that the games count, Waters has regained the itch to play.
The native Texan still was playing at a high level for the New England Patriots in 2011 before sitting out last season. With Nate Livings lost for the season, Ronald Leary questionable for the opener and Doug Free oscillating between offensive tackle and guard, the Cowboys had a glaring need for stability on the interior of their offensive line.
It likely will take Waters a few weeks to work his way into football shape. Once that happens, he should push Leary and Mackenzy Bernadeau for snaps at guard, allowing Free to kick back outside to offensive tackle.
