He needed no jolt of caffeine to get going, just a reminder of how his 2005 season ended, with a late September leg injury. "It's been a long time since I've been on the field, so that's motivation," he said. ''It was a rough injury." And it's been a rough road back to health. Light hoped to return to action late last season, but a setback in his rehab kept him on the sideline. Seven-plus months after suffering the initial injury, having tossed his crutches aside, he believes he's turned an important corner. this is certainly good news.
