Dabo Swinney says Clemson's four first-semester freshmen have made smooth transitions to college and have proved to be welcomed additions to his team. "I appreciate how they've plugged in," Swinney said. "They're four quality, quality guys - four good, fluid athletes. They're all serious about being successful. We've not had one issue with any of them. They've done everything we've asked of them ever since they've been here.
