1) Dallas Cowboys' offensive line
The offensive men in the trenches frequently get overlooked, but the Cowboys' front line deserves attention due to its consistent dominance at the point of attack. The unit features three former first-round picks (Tyron Smith, Zack Martin and Travis Frederick) and a gifted interior blocker (La'el Collins) who was rated as a first-round talent before a pre-draft ordeal -- one that saw him mentioned in conjunction with (but never seen as a suspect in) a shooting death -- made him go undrafted. With the team expected to show a renewed commitment to the running game, given Ezekiel Elliott's addition to the backfield, the football world will fully appreciate the Cowboys' O-line in 2016.
