Larry Allen, one of the most dominant offensive linemen in the NFL during a 12-year career spent mostly with the Dallas Cowboys, has died. He was 52. The Cowboys say Allen died suddenly on Sunday while on vacation with his family in Mexico. Allen was named an All-Pro six consecutive years from 1996-2001 and was inducted into the Pro Football of Hall of Fame in 2013. He said few words but let his blocking do the talking. Allen once bench-pressed 700 pounds and had the speed to chase down opposing running backs.
