Kosier joined the Cowboys in 2007 and has been a vital leader on the line ever since. In general, he makes all the calls for the O-line. Frequently, he is referred to as the “glue”. Certainly, he’s on the back end of his career, but the Boys are hoping he can give them a few more productive seasons as well as mentor young guard, David Arkin.
However, even with Kosier on board, the Cowboys will have to make some decisions about right guard. As of now, that job would probably go to Montrae Holland, which probably isn’t good for anyone. It’s doubtful that Arkin is ready to take over this year, but he’s going to be in the competition nevertheless. Bringing in another free agent is definitely a possibility too.
