Cowboys' guards switch sides

Wrote something on the Dallas Cowboys' offensive line earlier today, but as Ferris Bueller said, life moves pretty fast. If you don't stop and look around once in a while, you could miss it.

It's unclear whether it's a permanent move or just a temporary one until Holland is healthy (or another solution is found at right guard). But if Arkin and fellow rookie Tyron Smith are going to be starters on the offensive line, the new alignment makes sense for a number of reasons.

Kosier assumes a lot of responsibility for the line calls in Dallas' offense, and he has been given a degree of credit for helping Doug Free last year in Free's first season as the starter at left tackle. Since Free now has a year under his belt at that spot, it makes some sense to think that his communication and leadership skills could be put to better use on the right side, next to first-round pick Smith as he learns the offense. Certainly, it makes more sense to pair Arkin with the more experienced Free, and Smith with the more experienced Kosier than it does to pair the mutually inexperienced Arkin and Smith together on the same side.

Regardless, the upshot appears to be that, with Leonard Davis cut and Holland injured, Arkin has a real chance to be one of the Cowboys' starting guards in 2011. On one side of the line or the other. We'll see, as the preseason rolls along, whether or not he can take advantage of this chance.
