It is 1/2 way thru their rookie years, both of them don't know what they don't know. Coples is playing a tougher position playing on inside the tackle's shoulder. And Jones is playing more and mostly due to playing more is producing more.
TV people see Jones lining up wide and bending and turning the corner quickly and it just looks good, very easy to spot and plain to see on TV. Coples lines up on the tackles shoulder, making it much more difficult to get around the outside shoulder. If coples takes the inside shoulder and the OLB don't set the edge on the run, it looks like the DE got trapped inside.
With rookie Dlineman, your going to get wild swings in performance from one game to another and sometimes one play to another.
Dbrick did a very good job on Jones, but that is what you should expect when a rookie goes against a 10mill LT. Coples was very effective but both guards Mankins and Connolly were out.
It is extremely premature how anyone can label either at this point.
