From Daniel Jeremiah at NFL.com:
Graham is a powerful defensive tackle with outstanding leverage and instincts. He’s one of the most consistent players in the draft class. Against the run, he has an impressive short-area burst to attack blockers. He excels in block destruction. He stacks, finds the ball, chucks blockers to the side and collects tackles. He has lateral range to make plays down the line, too. He is always in a leverage position and never gets uprooted. In the pass game, he has a violent club/rip move and a powerful bull rush. His effort is outstanding.
