1. Team officials have mentioned trying to build a dominant offensive line that can mimic the Dallas Cowboys'. How did the Cowboys do it? They used the ninth overall pick on top left tackle Tyron Smith in 2011, the 31st overall pick on standout center Travis Frederick in 2013 and the 16th overall pick on stud guard Zack Martin in 2014. Their other starting guard, La'el Collins, is a first-round talent who went undrafted in 2015 because of significant off-field issues. Their other starting tackle, Chaz Green, was a third-round pick in 2015. That's a ton of assets spent on an offensive line, but the Cowboys have used them to build the best unit in the game.
