Cowboys bring back Kyle Kosier

For the second night in a row, the Cowboys agreed to terms on a new contract with a key piece of the left side of their offensive line. This time, it's left guard Kyle Kosier, who will return to Dallas on a three-year deal worth about $9 million. Tuesday night, they reached agreement on a new deal with left tackle Doug Free.

The Cowboys' focus this offseason was going to be on defense, and in the end it will be. But these two offensive line moves were critical at the outset of free agency. Free was the big name everybody thought they had to keep, but Kosier makes a lot of the line calls from his spot on the left side and was a big help to Free last year in his transition from right tackle to left. With right guard Leonard Davis being cut and center Andre Gurode revealing that he had knee surgery last month, the Cowboys may still have some work to do on the interior of the line. But Free and Kosier were the two key moves, and each seems to have been pulled off without much difficulty.
