Kid struggled to see the field at UNT and has 1 career start.....don't think he's here to compete for a job. One thing to have depth, another to have quality depth. Seems like this kid fits the former IMO.
OL is not just about individually winning the battles at LOS, Mainly is how you coordinate with the OL next to you to communicate, help-out, fill-in, switching, double teaming, audible, etc. Work as a unit is the term for OL group. DL on the other hand is more about individual strength, disruptive, burst, explosive, quickness, speed, etc.
Having the younger brother playing together before should be a positive thing.
