Will Muschamp isn’t a one-scheme man.

He’s long known for his 3-4 and 4-3 defenses and mixing elements throughout, and he’ll look to build Auburn’s defense into a stingy powerhouse. History tells us that will happen, because it’s happened everywhere he’s been.

Auburn’s defensive hybrid position under former defensive coordinator Ellis Johnson was the Star, a hybrid safety/linebacker role, but Muschamp will introduce a new hybrid position this spring: the Buck.

The Buck is a hybrid defensive end/linebacker who lines up at different spots on the field depending on what scheme the defense is running. If it’s a 4-3, the Buck lines up as a regular defensive end, but if there are more 3-4 elements on the defense, he’ll line up at outside linebacker and different spots on the field.

It helps create a mismatch and disruption nightmare.

Over the last three years, Muschamp had one of college football’s best defenders in Dante Fowler. You’ll see him likely picked in the top 10 of this year’s NFL Draft. Fowler was a massive disruption. Yes, the Buck position helped put him in positions to succeed, but he also possessed elite athleticism and skills uncommon to the average player. He recorded 15 tackles for loss and 8.5 sacks in 2014. He was the lifeblood of the Gators’ defense.

So, who will Muschamp’s catalyst Buck linebacker be at Auburn?

There are two players to key in on for 2015. This spring, however, the focus should be on returning defensive end Carl Lawson. Coincidentally, Lawson is nearly the same size as Fowler, who was listed at 6-3, 261 pounds on Florida’s roster. Lawson is listed at 6-2, 261, and he missed the 2014 season due to a knee injury. He made 20 tackles, including 7.5 for loss, as a freshman in 2013.

Muschamp believes Lawson will be available for most of the spring drills.

“He’s moving around extremely well,” Muschamp told the Columbus Ledger-Enquirer Friday. “We expect him to partake in a good bit of spring. How much will be determined by our doctors.”

Lawson’s return and development at the position could help take the Tigers’ defense to another level.

While Lawson is the immediate player to watch, the Tigers will welcome five-star talent Byron Cowart. Cowart’s idol was Dante Fowler, and his play in high school was more dominant than Fowler’s. Although Cowart’s frame is slightly larger than Fowler’s exiting high school, he has that rare ability to play with his hand up or down and will garner playing time immediately at the position.

Expect both Lawson and Cowart to be roaming the field for the Tigers this fall and wreaking havoc at Muschamp’s Buck position.
