IMO one of Dallas weaknesses in the run has been on the edge.
When Parsons gets run on, he isn't the best at setting the edge. Cardinals 2 years ago ran on his side often.
Against the Ravens, Dallas edge ate on a lot of inside fakes and left the edge wide open.
Fowler is back, but he's more of a pass rusher than run stopper. Same with EZ, at least early on.
Will linebackers with more a run first mindset help? Sure, but if the line can't win their battles or be in the right spot, it can be a mess again. Mazi could become a legit 1 tech but if the edge is open all day, he can't be superman and run down a RB headed to the 7 or 8 gap
