2011 Los Angeles Under Armour Combine: Top Performers, Testers and Sleepers

Bleacher Report was live on hand at the 2011 Under Armour Combine in Los Angeles this past weekend. The two-day event took place at Santa Monica College and included some of the top players and athletes on the West Coast.

At a well-ran event, the players went through rigorous physical testing, were spoken to about their academics and character development, and of course took part in positional drills, one-on-ones and even a seven-on-seven throwing session. Offensive and defensive linemen took part in their one-on-ones and also competed in a spirited Lineman's Challenge.

Come inside to see who all performed well, who dominated, who timed well, and a few sleepers to watch out for.

Top 40 Time: Naccarato and Leal Tie for Top Speed-Demon Honors

The combine had its fair share of speedy players, but Chase Naccorato, a wide receiver fro Spokane (WA) and Jordan Leal, a linebacker from Phoenix (AZ) both turned in 4.55 times in the 40-yard dash.

Naccarato is an undersized receiver at 5'8", 150 pounds, but is the type of player that you see at the next level that annoys defenses. He has the speed, quickness and agility to become a solid slot reciever somewhere on the next level. He' a sleeper pick of mine that I watched and compared to a poor man's Jordan Shipley.

Leal is a 5'10", 200-pound linebacker that has the speed and athleticism to transition to strong safety in college.

Top Short Shuttle: Wrout Wreaks Havoc

Tanner Wrout, a 5'11", 195-pound running back/outside linebacker from Rio Mesa (CA) produced an outstanding 4.19 short shuttle time at the combine.

Wrout also tossed up the bench 12 times and jumped 27 inches on the vertical jump, displaying solid all-around athletic ability to likely play running back in college.

He was followed up on the short shuttle by Jordan Leal, as aside from Leal's top 40 time, he finished second overall in the short shuttle at 4.22.

Top Bench Press: Greene and Anderson Display Strength at LA Combine

Brandon Greene, a 6'2", 250-pound offensive lineman, and Darek Anderson, a 5'10", 260-pound defensive lineman, both threw up the bench press 27 times, showing great upper body strength.

Greene has the makings of a solid center propsect that has the strength to anchor in the pivot. He also showed solid athletic ability to pull and trap during positional drills.

Anderson is a bowling ball type of defensive lineman, that lacks ideal height, but understands that leverage is key to winning battles.

Top Vertical Jump: Naccarato Jumps Head and Shoulders Above the Rest

Naccarato was back at it again at the vertical jump, showing why he will make the "underrated" portion of my board. The 5'8", 150-pound receiver stepped up to the vertical jump portion of the testing phase of the combine and jumped a remarkable 35.5 inches.

Naccarato drew my attention when I saw him moving with speed and quickness in the L-cone drill, where he blazed a 6.84 time. He just hows the potential to be a solid slot guy for somebody, maybe not a big school, but somebody can definitely use his skills.

Top L-Cone Time: 2013 Top Running Back Khalfani Muhammad Is Best

I went and watched Muhammad play as a sophomore last year and I came away very impressed with him. When I spoke with him after the game, he seemed like a player that was convinced that a hard work ethic is the key to success.

When I saw and spoke with him again at the combine, it was clear nothing had changed. Muhammad shook out a 6.84 L-cone drill time that is a fantastic mark and took top honors in the drill. He's a 5'8", 160-pound change-of-pace back that won't be a senior until 2013.

Put Muhammad down as a junior player to watch this season.

Top Performers: Offensive Skill Players

The big draw on the offensive side of the ball was Lakewood (CA) receiver Malik Gilmore. Gilmore boasts six offers already from stellar programs that we will get into later, and is a physical marvel.

At 6'3", 200 pounds, Gilmore has very long arms and mits for hands. During the one-on-ones and seven-on-sevens, he showed physicality at the line, solid release quickness and very good ball skills.

At running back, the man was Khalfani Muhammad again. NFL legendary running back Barry Foster, who served as the combine's running backs coach, personally told me, "(Khalfani) is a beast. That kid is real nice. Wow." Muhmmad annoyed linebackers all day by showing he's unhittable at the junction point, quick out of the bakfield and has very good hands for a running back.

Quarterback was more of a committee type of group, with Roosevelt (CA) signal-caller Aaron Crone leading the way. Crone (6'0", 190 pounds) has a quick release, strong arm and solid accuracy. He showed good touch during the throwing sessions.

Robinson also had a solid day throwing the ball. The 6'0", 160-pounder from Mira Mesa (CA) is scheduled to take part in the famous Elite-11 QB workout this summer.

Top Performers: Defensive Skill Players

At linebacker, I really liked Chris Santini, a strong safety/rover/outside linebacker hybrid defender from Leland (CA). At 6'1", 200 pounds, Santini, who is close to his first offer, moves well around the field, has very good quickness in his cover drops and will come up to play the run. We will have more on him later as well.

But the defensive player that impressed the most was cornerback Johnny Johnson. At 5'10", 170 pounds, Johnson was incredibly physical. He flashed deceptive strength to press and the line and was a bully for receivers all over the field.

The matchup of the day was Malik Gilmore vs. Johnson, and Johnson got the best of Gilmore by pressing him at line, forcing Gilmore to slip—and Johnson just mauled him from there. Johnson won't be a senior until 2013, but he's already hearing from several FBS schools.

Top Performers in the Trenches for Offensive and Defensive Linemen

Mario Yakoo from Steel Canyon (CA) and Eric Rodriguez from Palmdale (CA) were both the top offensive linemen performers. Yakoo held his own during one-on-ones, walling off rushers and sliding well when engaged.

Rodriguez showed the ability finish blocks well as run blocker and pass protector when rushers tried to bend off the edges and corners on him to finish in the pocket.

There wasn't a dominant defensive lineman on hand, partly because Yakoo and Rodriguez handled everyone who was thrown at them with ease.
