The summary on Jolly from NFL.com's Prospect Profiles:
"Jolly was a tough player to fairly evaluate because despite his natural tools, he does not finish and make plays that he gets close enough to on a regular basis. He does a good job of bending his knees and playing with leverage, which allows him to hold his ground at the point of attack on runs at him, but he does not shed the blocker quickly enough to make the play and too often he is tied up right as the ball carrier runs right by him. He does a good job of getting off the ball and into the backfield to disrupt plays, but he does not finish and make the play often enough. Overall, Jolly has all the physical tools to be a good starting defensive tackle in the NFL, for a 3-4 or 4-3 defense, but will need to use his hands better to take on and shed blockers. Additionally, he will need to play with that aggressive, attacking style much more in order to produce at the level he is physically capable of. I believe that Jolly will be drafted later than he is evaluated here, but given a season or two as a backup (possibly even on the practice squad), he can become a good backup defensive tackle who can do a solid job of spot starting when needed."
