Hopefully for the Tennessee Titans, Vince Young learned a very important lesson Wednesday in training camp. Never, ever throw a punch again with his throwing hand. Luckily for the 2006 offensive rookie of the year and the Titans, the punch thrown at safety Donnie Nickey glanced off his helmeted head. "The guys stick up for the quarterback, and he sticks up for his teammates," coach Jeff Fisher said. "Enough said." Young has never hid his competitive spirit, whether back in college at Texas or since being drafted last year by the Titans. During training camp last year, he leveled defensive tackle Randy Starks after having a pass intercepted.
