5 College Football Teams Building Nastiest Defensive Groups in Class of 2014

College coaches across the country continue to comb the class of 2014 recruiting landscape in search of tomorrow's top stars. National signing day looms large on the horizon so every commitment helps at this point, particularly when it's a polished player with a defined position.

These recruits match the description of instant-impact prospects and can be counted on to contribute early and often upon their arrival. Coaches are always in search of these playmakers on the defensive side of the ball to combat evolving offensive schemes.

Some squads have already scooped up substantial recruiting hauls on defense, setting the stage for success in future seasons. Here's a look at programs primed for defensive dominance based on their 2014 class.

B/R college football columnist Tyler Donohue spent three seasons with the Rutgers University football program's recruiting department, contributing to three classes (2007-09) under head coach Greg Schiano.

Michigan

Brady Hoke appears to have bolstered his defensive personnel with this group, highlighted by New Jersey wunderkind Jabrill Peppers. The defensive back and return man is a five-star prospect and the nation's third-best player, according to 247Sports composite rankings.

He figures to find a starting spot at cornerback or strong safety when he arrives in Ann Arbor. Peppers has been on the national recruiting radar since he was named the U.S. Air Force National Sophomore Player of the Year.

He'll be joined in maize and blue by a myriad of defensive talent.

Ohio product Michael Ferns is listed as the sixth-best inside linebacker in the country in 247Sports composite rankings. He displays a tremendous motor and hammers running backs by identifying gaps.

Defensive lineman Bryan Mone and Lawrence Marshall are each four-star recruits in 247Sports composite rankings. Marshall, a 6'3", 230-pound weak-side end, initially committed to rival Ohio State before changing his mind.

Virginia

Virginia prevented two of the nation's top players from departing the state.

The Cavaliers have made quite a splash on defense as the squad aims to make strides in the ACC. Virginia only holds nine commitments at this point, but its 2014 class is incredibly strong at the top.

The team landed one of the best players in its state when Andrew Brown committed in late June. The 6'4", 280-pound Chesapeake resident is considered the No. 1 defensive tackle prospect in 247Sports composite rankings.

Brown is more physically advanced than most prospects at the position, devoid of "baby fat" and brimming with strength. He is tailor-made to play the 3-technique and reminds me of former Oklahoma star Gerald McCoy.

The Cavs also pounced on Virginia Beach standout Quin Blanding, who sits atop the national list of safeties in 247Sports composite rankings. The 6'2, 200-pound thumper has the speed and size to play either safety position.

It would be a disappointment if Brown and Blanding weren't both starting by the end of 2014. 

Florida

The Gators gain tremendous defensive talent in the 2014 class, especially along the secondary.

J.C. Jackson (Immokalee, Fla.), Chris Lammons (Plantation, Fla.), Quincy Wilson (Fort Lauderdale, Fla.) and Duke Dawson (Cross City, Fla.) are each considered four-star prospects and among the top 247 players in the nation according to 247Sports composite rankings.

Although one of these standouts is likely to line up at wide receiver—possibly Jackson—this incoming group figures to reshape Florida's secondary structure in the near future.

Jackson and Lammons are tailor-made for cornerback, while Wilson and Dawson may be destined to form a dynamic safety duo. Jackson decommitted from Florida State in June.

Dawson is a heat-seeking missile and Gator fans will fall in love with how he finishes hits with his feet pumping. Expect him to challenge for playing time at free safety as a freshman.

Along the line, the Gators grabbed Hollywood, Fla. defensive tackle Khairi Clark. The 6'2", 325-pound nose guard is a four-star recruit and considered the nation's ninth-best prospect at the position, according to 247Sports composite rankings. 

Clark is joined up front by menacing 6'5", 250-pound defensive end Tavin Bryan, who Florida wrangled all the way from Wyoming. Bryan could get strong consideration to play offensive tackle but he would make an ideal 5-technique in the Gators' defensive system.

Tennessee

The Volunteers have put together one of the best all-around recruiting classes in the country, so it's no surprise Tennessee is pulling in top defensive talent. Chris Weatherd, Kevin Mouhon and Dillon Bates bolster the linebacker corps, providing the team with a trio of potential defensive anchors.

Bates, a 6'3", 220-pound Florida recruit, is excellent in pass coverage and among the best in his class at wrapping up tackles. He still has plenty of progression to make as a pass-rusher, but is well suited for a future at outside linebacker.

Weatherd is considerably more polished. The 6'4, 225-pound Texan comes to Tennessee with a chance to start as a freshman due to his freakish sideline-to-sideline pursuit and penchant for disrupting the passer.

Both Bates and Weatherd are considered four-star recruits in 247Sports composite rankings. Weatherd is listed as the No. 1 outside linebacker in the nation, per those rankings.

Mouhon, a 6'2", 225-pound thumper from Georgia, is a prototypical middle linebacker. He rarely gets caught up in a block, holds his own against running backs in pass coverage and is clearly diligent in his pre-snap gap assessment.

The three linebackers lend immediate special teams support at Tennessee and are expected to be significant factors throughout their time in Knoxville. They'll have the support of top-flight 2014 defensive backs.

Nashville's Rashaan Gaulden gives the Vols a versatile option at safety and is one of the most underrated secondary players in the 2014 class. Knoxville native Todd Kelly spurned offers from Alabama and Arkansas to stay home.

Kelly, the son of former Vols standout Todd Kelly Sr., is considered the country's sixth-best safety prospect, according to 247Sports composite rankings.

Tennessee is building something special up the middle of its defense with this recruiting class.

Alabama

The Crimson Tide have a proud history of superstar defensive stalwarts. That tradition appears to remain intact judging by Alabama's latest recruiting efforts.

The team continues to replenish its defense with this class, highlighted by a great haul in the secondary. Kalvaraz Bessent, Stephen Roberts and Chris Williams fit the mold of defensive backs in Nick Saban's system, one that has churned out top NFL prospects on a regular basis.

Bessent, the nation's 10th-best cornerback according to 247Sports composite rankings, doesn't rely solely on his speed in coverage. The 6'0", 170-pound Georgia recruit is an absolute bump-and-run cover man, who plays physical downfield without crossing the line and drawing penalties.

Roberts is almost an identical prospect in terms of approach. 247Sports composite rankings list him as another 4-star for Saban and he could force his way onto the field early as a threat in the special teams return game.

Williams will overachieve at Alabama, where safeties are valued more than almost anywhere else in the country. Another Georgia recruit, Williams closes space in a hurry and plays with reckless abandon, a trait that could ultimately be a double-edged sword until he settles into the scheme.

Linebackers Shaun Dion Hamilton, Zach Whitley and Christian Miller are among the nation's best and fit the bill as tall, physically imposing defenders in the Tide defense. Each player brings a different specialty to the field.

Miller, listed as the second-best outside linebacker in America according to 247Sports composite rankings, is a monstrous 6'4, 225-pound playmaker from South Carolina. He projects as Alabama's premier stand-up edge rusher and could occasionally line up with his hand in the dirt.

Hamilton and Whitley are more inclined to play inside, where there should be room for both players to earn a spot. Whitley, a Texan, and Hamilton, an Alabama native, are both considered top-10 inside linebacker prospects according to 247Sports composite rankings.

When you add it up, Alabama is welcoming in three top-tier linebackers. That's a recipe for continued defensive dominance in Tuscaloosa.
