Veteran Atlanta Falcons linebacker Stephen Nicholas struck just the right tone for the audience of high school football players and their participating coaches Thursday during the NFL’s High School Player Development Camp at East Hall. After a day of serious seminars geared toward teenage football players in the 21st century, just shy of 500 football players from nine northeast Georgia schools heard Nichols wrap up the first of the two-day camp in Gainesville talking about commitment, character and making good choices. “If this sport helps you get a college education, play it,” Nicholas said in a straightforward voice with a constant sweat rolling down his forehead in the Vikings basketball gym.
