I think the area in which I would like to see Jones make the biggest improvement relates to his performance against some of the bigger, heavier tackles in the game. Understandably so, some of his offensive tackle opponents outmatched his weight by significant margins. Jones did not have the power to explode through the better OTs with traditional bull-rushes. Call it a weakness in his play or an opportunity for improvement, the lower body weight gains from this offseason should diminish this nitpick.
It reflects the already known weakness to the lighter DE trends: OTs are getting taller and heavier. At least we've got our own two towers on the O-line.
