From his Combine 2012:
STRENGTHS
Cornick is a very good run blocker who, despite his size, is flexible in his stance and has consistently shown the ability to out-leverage his man at the point of attack. He is a competitive blocker and finishes downfield on every run play. He is technically sound with his hands, and once a man is engaged he is rarely released until the whistle. He is a decent athlete who relies more on his preparation, savvy and game day tenacity as a blocker, all the more reason why he should thrive if moved to the inside of the line. His footwork as an edge blocker lends well to his projectability to guard in terms of pulling and working up field to block linebackers.
WEAKNESSES
Cornick does not seem capable of playing outside as a tackle in the NFL at this point in his career. In pass protection, he sits very tall, and although he hasn't had anchor issues, it's likely he could get blown back by bigger defensive ends when using this technique. Paul is limited athletically and will have to make an impression through strength and competitiveness; his ability to adapt to the speed of the pro game will be the driving force behind his development and transition from North Dakota State.
