Allen Park -- Training camp is upon us. The Detroit Lions' rookies report this week and veterans will follow a week later. We're going to spend the next few days previewing camp, starting with the team's five most compelling position battles.
The most intriguing opening in Detroit’s starting lineup remains at guard, but the hole appears to have shifted to the left side with Graham Glasgow sliding into T.J. Lang’s former spot. Obviously, there’s still plenty of time for things to change, but that’s been the primary practice routine for Glasgow at this stage, with Frank Ragnow, entering his second season, working at center.
