Guyton is a fast player with a motor that doesn't stop, which has helped him be an active player in his senior year and gives him sixth-round value in the draft.
He really sets the tempo off the ball and has the ability to quickly blow back lineman. He is excellent in pursuit in the open field, where his speed really shows up. He is a sure tackler who has been around the ball often in his senior year.
Although teams understand Guyton's being caught behind first-round picks Cameron Jordan and Tyson Alualu, they will wonder if he's truly the player with the skills he displayed in his senior year, or just a pretender who showed up to play only once his draft status was on the line."
Instead of redshirting his first year on campus, Guyton played the final seven games, making three tackles (two in the prestigious Big Game match-up against Bay Area-rival Stanford). He saw more action in Cal's defensive line rotation in 2009, earning 13 tackles, four of them for losses including a sack. While he did not start until the last four games his junior year, Guyton was named the team's Most Improve Defensive Lineman after being credited with 29 tackles, 8.5 for loss and 4.5 sacks.
It will be easy for NFL defensive coordinators to like Guyton's mix of strength and hustle, whether they project him as a 4-3 under tackle or 3-4 five-technique. He may remind scouts more of former Bears third-round pick defensive tackle Brandon Mebane than Alualu or Jordan, but with some improvement shedding blocks to make more plays as a senior, he could be yet another Cal lineman earning top 50 draft grade.
Pass Rush: Not elite in this category, but possesses good quickness and change of direction skills to bring down pocket passers or chase mobile quarterbacks out of the pocket. Most effective getting pressure when using his quickness on the nose, also uses quickness and strength to pressure the inside lane against left tackles from five and seven technique spots. Penetrates into the backfield with bull rush against lesser linemen or getting his shoulder under his man's pads while chasing a gap. Relies on long spin move to get off blocks, needs to use his hands more consistently to rip and move forward. Mobile quarterbacks elude him too often for him to get double-digit sacks.
Run Defense: Hustle run defender who chases down ballcarriers to the sideline and downfield. Despite owning only average bulk, plays with leverage on the nose, holding his position against good centers and double teams. Runs over cut blocks, stays active to chase from the back side. Must improve his ability to get off blocks inside to stop backs coming through the hole. Loses the ball on misdirection at times due to aggression attacking his opponent and lack of height.
Explosion: Brings nice quickness off the snap in passing situations. Comes low and strong against taller linemen, gets under their pads to get into the pocket. Could be very effective as a tilted three-technique position with his nice first step, less straight-on attacks.
Strength: Plays with very good leverage at the point of attack, rarely gets pushed back when man-up after the snap. Usually ends up on the offense's side of the line against lesser competition; stronger linemen hold back his advances more effectively. Inconsistent anchoring and staying upright when turned in the hole; may need to add some bulk and strength to move or maintain his gap against pro linemen (or may just be best in a one-gap system).
Tackling: Strong tackler in tight quarters with agility and thick upper-body strength. Gives excellent effort to chase plays down the line and downfield, even when ending up on the ground at some point during the play. Defeats cut blocks with nice balance and good hands, almost always stays upright and recovers quickly when on the ground. Does not make a lot of stops, though, because he is usually inside the tackles and lacks violent hands to shed. Agile enough to break down against elusive backs and quarterbacks, but they run through his tackle attempts too regularly.
Intangibles: Very good on-field effort. Praised by coaches for his attitude, hustle, and work ethic in practice. Missed time in 2009 with an illness."
When lined-up inside exhibits a plus first step and when he keeps his base down and back straight he not only can anchor inside, but has the lower body strength to overwhelm on contact. Possesses strong arms as well, works his legs through contact and can clog up run lanes inside.
Is still learning how to use his hands consistently to shed inside, as he gets a bit upright and loses balance when trying to disengage. Also, needs to do a better job finding the football.
Puts himself around the action routinely to make impact caliber plays vs. the run, but struggles to routinely find the football. However, started only the final four games of the year and awareness should improve with experience.
Will line up outside in pass rushing situations, needs to do a better job playing with a flatter back off the line as he buckles over at the waist and his initial movement is often upright. However, can be violent with his hands when trying to rush the passer, plays with a mean streak and has a good motor in pursuit.
Isn't an overly sudden lateral athlete, but is balanced when looking to change directions and keeps his feet under him. Stays active with his hands and can keep himself clean inside when trying to work toward the QB. When he fires off the ball low he routinely creates a good initial bull rush inside vs. the pass.
Displays only average closing range in pursuit in all areas of the game and is still learning how to shed with his hands and disengage through contact inside.
Impression: A guy who can fill a number of roles on a defense, but he's a naturally powerful kid who can anchor and overwhelm vs. the run game. Needs to improve hands and awareness, but the upside to make a roster."
Plays with leverage, as he generates power through his base, stays square and controls single blocks, although he is slow to shed.
Tends to duck his head and winds up on the ground more than he should.
However, he is an intense, high-motor player who is capable of doing the dirty work as a 3-4 five-technique or could even appeal to 4-3 teams as an interior player.
Has desirable intangibles and could take his game to another level with improved hand use."
Built low to the ground with excellent strength; gets off the snap with authority and uses hands well to disengage;
Also has good balance and can change direction; best asset, though, is a great motor;
However, not a particularly good athlete and only has limited closing speed and lateral range."
Negatives -- Not an elite athlete nor pass rusher, limited athlete with inconsistent hand usage, can be slow to get off blocks and mobile quarterbacks will elude him, has just 10 career sacks and never more than 4.5 in a season, isn't a finished product as a pass rusher and possesses a limited arsenal of moves; average closing speed, needs to throw his hands up in passing lanes if he can't get to the quarterback... Can be a non-factor versus stronger linemen; Guyton has good potential but lacks consistency... Can be over-aggressive at times and will be fooled by misdirection plays, is very instinctual, but will take false steps and get slightly out of position when anticipating incorrectly, overall range is limited due to lack of athleticism... Did not start until the final four games of his junior season."
