5. Caullin Lacy
Caullin Lacy is coming alive at the perfect time. The speedy wide receiver is an elite punt returner and is becoming a huge deep ball threat. Last week's win over Boston College was the game the fans had been waiting for, courtesy of Caullin Lacy. He earned another receiving touchdown as he earned a 24-yard receiving touchdown in the third quarter, followed by showing off his speed on special teams yet again as he returned a punt 63 yards to the Hokies' 5-yard line, setting up Keyjuan Brown for a rushing touchdown.
Lacy is the biggest X-factor on this team, as he isn't just a threat on offense for the deep ball, but also on special teams. His ability to break loose and score or put Louisville in scoring position is crucial with Brown out.
Lacy has logged a receiving touchdown in consecutive weeks after not earning a receiving touchdown in the first six games. Lacy has to keep seeing more touches with Brown out, whether that involves WR screens or more looks down the field, but he is emerging as a true threat.
