Marquardt is a steady, powerful defender who enjoyed two excellent seasons with the Sun Devils, starting all 23 games he played in Tempe. He not only excelled as a run stuffer in the middle of the field, but also earned Academic All-Pac 10 Conference honors twice. He was a semifinalist for the 2007 Draddy Trophy, nicknamed the "Academic Heisman."

The talented defensive tackle comes from a family of defensive linemen. His father, Peter, played football at UCLA. One of his brothers, Daniel, was a teammate and defensive tackle at Brigham Young (2001-05) and another brother, Brian, competed as a defensive tackle at Weber State.

Marquardt earned Prep Star All-American honors as a senior at Rancho Buena Vista High School. He added All-CIF and All-League recognition and was named the Palomar League Most-Valuable Player as a senior. He ranked as one of the top two linemen in the state of California and was listed as "one of the top defensive line prospects in the country" by Prep Star. He produced more than 40 tackles as a senior, including a team-leading 18 sacks and four forced fumbles, returning one for a touchdown.

Marquardt enrolled at Brigham Young in 2000, but spent the season on the sidelines recovering from a left rotator cuff spring. He appeared in 10 games in 2001 as a reserve defensive end, collecting 11 tackles (9 solos) with three sacks and five stops for losses.

After spending the next two seasons serving on an LDS mission to Argentina, he returned to the gridiron at Brigham Young in 2004, appearing in 10 games. He saw limited action as a reserve defensive end, posting five tackles (3 solos) with a stop behind the line of scrimmage and two pressures.

Feeling he needed a change of scenery in a quest for more playing time, he left BYU and transferred to Arizona State in 2004, sitting out the season under NCAA transfer rules. In two seasons with the Cougars, he produced 16 tackles (12 solos) with three sacks for minus-27 yards, six stops for losses of 33 yards and three pressures in 20 games.

Marquardt started 12 games at left defensive tackle for the Sun Devils in 2005, missing most of the Southern California game with a neck injury. He was a first-team Academic All-Pac 10 pick, adding honorable mention for his field performance. He totaled 25 tackles (18 solos) with 3 ½ sacks and 7 ½ stops for losses.

In 2007, he again earned honorable mention All-Pac 10 Conference and academic all-league first-team honors. He started 11 games at left tackle, sitting out vs. Oregon State and Stanford with an ankle sprain. He posted 23 tackles (11 solos) with 1 ½ stops behind the line of scrimmage, two fumble recoveries and a blocked kick.

In 24 games at Arizona State, Marquardt started 23 contests. He recorded 48 tackles (29 solos) with 3 ½ sacks for minus-20 yards and nine stops for losses of 36 yards. He recovered two fumbles, advancing one 3 yards, deflected a pass and blocked one kick.

Positives: Has adequate muscle tone and a frame that can carry at least another 20 pounds of bulk without the additional weight affecting his agility … Best when used in a rotation system to keep him fresh … Speed is limited, but he has good initial quickness off the snap to gain advantage on a lethargic blocker … Keeps his hands active to defeat low blocks and shows good field vision to locate and close on the ball … Recognizes blocking schemes and makes good adjustments to combat them … Has the functional lateral range to work down the line in short-area pursuit … Has the hand strength to shock with his punch, but his overall power base is marginal-to-adequate … Active with his hands in attempts to disengage and has enough looseness in his hips to spin off blocks … Shows good urgency to pressure the quarterback, if he gets a free lane into the backfield (will struggle to split double teams) … Has good hand strength to wrap up and take the ballcarrier down … When he keeps his pads down, he has good success flashing off the snap to generate a quick gap charge.

Negatives: Has adequate agility and balance on the move, but lacks the timed speed and overall quickness to give chase on long pursuit … Uses his hands well to defeat blocks, but his overall strength level is marginal for a player his size … Over-aged prospect who will be 26 by the time he arrives in 2008 training camp … Lacks the second step to impact the backfield after he sheds the block … Even when he gets into the backfield, he will not be one who can constantly pressure the pocket due to poor speed … Has good lateral moves working down the line, but looks sluggish redirecting after he plays off a block … Shows good body control making a tackle, but does not show the raw power to explode behind his hits … When he comes off the blocks high, he is instantly pushed out of the rush lanes … Has a strong hand punch, but lacks the technique to counter or beat blocks if his initial move fails.

Compares To: BRIAN YOUNG-New Orleans … Marquardt has good initial quickness off the snap, but is more of a stay-at-home type who is best when the action comes to him rather than pursuing it. He has enough lateral range to flash down the line and when he stays low in his pads, he has decent gap penetration skills. He is just too slow to impact the pocket on a steady basis. He has a strong punch to shock and jolt, but poor technique in attempts to shed. He will need to get stronger and quicker if he hopes to get out of 2008 training camp with a roster spot, but he will be 26 by the time the season begins, a little late to start trying to rectify his deficiencies.

2000: Sat out the year with a left rotator cuff injury.

2006: Saw brief action vs. Southern California (10/14) due to a nerve problem in his neck.

2007: Sat out the Oregon State (9/22) and Stanford (9/29) games due to an ankle sprain.

Campus: 5.34 in the 40-yard dash … 335-pound bench press … 28-inch vertical jump … 30 ¾-inch arm length … 9 ½-inch hands … Right-handed … 19/34 Wonderlic score.
