The running game still has a prominent piece to be added at a later point. Right now, and with the fullback position...the stable is very productive already.
The defense is still a major work in progress. Getting Lawrence back this next game, won't hurt anything there. Getting Scandrick back, and with the improvements of the secondary, that defense will be getting tougher through the season. There will still be a need for additions this next season on the defensive side of ball, but Smith and Tapper should help out in a rounded depth picture.
There will be money spent on keeping the players Dallas has at cornerback, and safety...come the next off season.
A defensive line consisting of Tyrone Crawford, Maliek Collins, Terrell McClain, and DeMarcus Lawrence...well, projects and is developing.
Mix in Cedric Thornton, Jack Crawford, and David Irving, and there is an adequate rotation...but pressure still most become an active ingredient.
Third down effectiveness by the running game, and an over 70% - 3rd down completion rate by Dak Prescott, are very strongly projecting in the now!
