The Giants might have Saquon Barkley and Odell Beckham, but they also have an offensive line that has spent the last several seasons getting pushed into the backfield. Speaking of O-lines, the Cowboys will enter the season with a unit that has been ravaged by attrition and injuries since the 2016 campaign that saw them go 13-3. Three of the five starters from that group have moved on (Ronald Leary to the Broncos, Doug Free to retirement) or are battling serious health problems (all-pro center Travis Frederick has been diagnosed with a potentially career-threatening autoimmune disorder). It could be a long season in Big D, even if two-time all-pro guard Zack Martin recovers from a hyperextended knee in time for Week 1.
