Third Round, 82nd Pick
Longtime New York Giants general manager George Young's "planet theory" holds that there are only so many giant men with athletic ability on the planet, so you should get one when you can. Georgia defensive tackle John Jenkins has the giant part down at 6'4" 346, but is he athletic and productive enough to go in the first round?
Jenkins will instantly be one of the biggest players in the NFL, and he's not a slug. The big man will flash surprising quickness and he can actually run a little bit. He has very good stamina in game for someone who weighs near 350. Forget about moving Jenkins backwards with one-on-one unless you go at his legs. He will tie up double-teams and re-route running plays that enter his area. Even though he is massive, Jenkins can actually collapse the pocket and generate some pressure on the quarterback.
While quickness is there at moments, Jenkins isn't very sudden off the snap and rarely gets the drop on his opponent. He doesn't jolt his man back or otherwise generate a lot of force, and Jenkins also plays so high that it is pretty easy for a strong offensive lineman to neutralize him. Getting off blocks is also a problem for Jenkins, so he won't have much effect on a play if his initial attack is unsuccessful.
Once again, that 6'4" 346-pound frame with 34" arms is the main thing Jenkins has to offer. Thirty bench press reps at the combine shows you how strong he is, but he is more immovable object than irresistible force. It's not common, but you will see decent quickness from Jenkins off of the snap and very good feet for a giant.
Jenkins missed the last bowl game of his career because of an "academic issue." As with any player that weighs well over 300 pounds, conditioning and weight management are going to be issues. Jenkins was a community college transfer, so his experience at the top level of college football is limited.
Jenkins lined up at zero-tech nose tackle, five-tech defensive end and everywhere in between in the three-man front of Georgia's defense. He can play one or two-gap responsibilities and occupy two blockers when asked to.
You wouldn't expect much in the way of pass rush from a 346-pounder, but Jenkins gets very good push when he is one-on-one and can flush the quarterback from the pocket. He can even stunt/twist to cross up a disorganized offensive line. Jenkins looks very good as a bull rusher matched up one-on-one against less stout offensive tackles, and he can even get a good push against double-teams at times. He is too often easily neutralized when he plays high, and Jenkins also ends up on the ground a lot more than typical defensive line prospects.
Against the Run
Clogging up run lanes is what Jenkins does best. He can push his blocker back, but usually Jenkins just makes himself impossible to move. One exception is when blockers go low to cut-block Jenkins. He actually has decent balance and can avoid the block, but he gives a lot of ground to do it, and a second blocker can blast him back if he catches him jumping back to avoid the cut block.
For a large man, Jenkins is surprisingly good at flowing down the line to the play. He will generally have an effect on any run play near him, although he can pushed back by good angle blocking more than straight-ahead power blocks. Jenkins' long arms can slow down, if not stop a running back going through the hole.
Jenkins does a good job wrapping up with those 34" arms, and he can corral a running back by himself. Once he gets his hands on a back, the play is usually over.
Use of Hands
Jenkins is not very active with his hands, and this shows up when he struggles to free himself from blocks. Sometimes he doesn't even try to shrug off his blocker. Jenkins also fails to jolt his blocker back with a good sudden punch and in general is not violent at all with his hand usage.
Scheme Versatility/Future Role
Jenkins will surely appeal to teams that run 3-4 or multiple fronts with his rare frame to play two-gap nose tackle. He can also line up at 3-4 end or nose tackle in a 4-3 front, giving him a lot more versatility than his body type would indicate.
