OXNARD, Calif. -- When the Dallas Cowboys selected Tyron Smith in the first round of the 2011 draft, it was the beginning of a change in philosophy. Never before in the Jerry Jones era as the team’s owner and general manager had the Cowboys chosen an offensive lineman in the first round. It always seemed strange how Jones looked to build his offensive line considering he played the position on a national championship team at Arkansas and should know the importance of the position.
