Is there enough depth on the offensive line? That's a question folks were asking even before starting left guard Kyle Kosier and right tackle Marc Colombo suffered injuries. Colombo probably will return in time for the opener against Washington on Sept. 12, but Kosier could miss a couple of games. Veteran Montrae Holland (48 career starts) will replace Kosier. Holland's had his moments in the league, but he has started only two games since joining the Cowboys in '08.
Robert Brewster may get the start in Colombo's place, and that's a problem. Brewster's footwork has been questionable and he's getting blown off the ball in pass protection. And on Wednesday, the Cowboys couldn't seem to decide whether quarterback Tony Romo would play Saturday against the Chargers. The Cowboys are extremely talented at the skill positions, but a couple of injuries on the offensive line could derail this team. The good news is that left tackle Doug Free has had an excellent camp. Owner/general manager Jerry Jones believes that Free will be an upgrade over Flozell Adams. I think that may be the case down the road, but for now, Free's still somewhat of a wild card.
