Take into account he has played basically no football since he was drafted here and was a project to begin with. Sitting in on meetings and film does not equate to field experience. This horse has never left the starting gate. To expect anything at all at this point is being generous.
I predict Hardy will never have a fifteen sack season again, especially with Dallas. He benefited from a killer dline, as did the secondary in 2013. With the double teams he will see, maybe eight to ten a season max. That production can be had with the rotations we use. Not worth the hassle at all.
