Dallas coaches and players love to fawn over developing DT Tyrone Crawford. It appears that Dallas has reached the conclusion that they have two plus 3 techniques and that makes Melton and his contract very expendable.
I don't love this, as I think sacks are important, not just pressures, but I am OK with the decision value-wise ---as long as this defensive sacrifice it isn't about trying to resign injury prone RB DeMarco Murray.
Crawford's "position flex" is overrated. The three spot is a good one for him. Additionally, while I can appreciate what Melton is, I have never been as sold on him as other reviewers.
