National Signing Day 2012: 5 Teams Already Killing It Today

As National Signing Day begins to unfold, we sports writers at Bleacher Report are scrambling to get you the most recent commitment updates.

There are still many Top 300 players yet to come off the board, but some teams have grabbed one or two to further solidify their recruiting class.

Here are five schools that are having a great NSD morning.

Rutgers Scarlet Knights

South Brunswick High School standout Jevon Tyree signed with Rutgers this morning, following in the footsteps of dear friend Mohamed Sanu (leaving early for NFL draft).

The 5'10", 170-pound cornerback is rated No. 36 at his position, according to Scout.com.

Three-star wide receiver Ian Thomas also signed with the Scarlet Knights today, continuing the momentum for a strong official first day for new head coach Kyle Flood.

Oregon Ducks

Fort Bend Hightower (Missouri City, Texas) wide receiver Bralon Addison woke up this morning with second thoughts about his Texas A&M commitment.

Those second thoughts became third, fourth and fifth thoughts, and then ultimately swayed his decision with the Aggies as he signed with Chip Kelly's Oregon Ducks.

The 5'10", 180-pound U.S. Army All-American is the nation's No. 14 wide receiver, according to Scout.com. He had committed to A&M last May after decommitting from Oklahoma State.

Oregon also received a written commitment from another wide receiver from the Lone Star State Wednesday morning with Chance Allen. The 6'2", 190-pounder is No. 115 in the national rankings for his position.

Miami Hurricanes

The Miami Hurricanes received their letter of intent from five-star cornerback Tracy Howard at 9:50 A.M. this morning, reports Scout.com.

One of the nation's most heavily recruited CB prospects this year, Howard was expected to sign with either Florida State or Florida today. However, he was impressed with Miami head coach Al Golden and his "plan."

Howard is known for his elite coverage skills, possessing the ability to shut down even the most high-profile receivers. He runs a 4.40 second 40-yard dash and can bench 260 pounds.

His hometown is Miramar, Florida, which is 30 minutes away from the University of Miami campus.

Alabama Crimson Tide

Two four-star defensive ends have decided to play for Nick Saban and the defending national champions Alabama Crimson Tide so far today.

Korren Kirven and Dalvin Tomlinson are the No. 15 and 17-ranked DEs in the country, respectively. Both are outstanding pass rushers that will quickly contribute to what was arguably the best defense in the nation last season.

Both recruits were high school stars and had multiple offers from various SEC schools.

Missouri Tigers

The No. 1 overall recruit in the class of 2012 will be playing for the Missouri Tigers of the SEC East next season.

Dorial Green-Beckham has drawn comparisons to the NFL's best wide receiver Calvin Johnson and the big-time target (6'6", 220 pounds) has every necessary asset required to play at the next level.

He holds the national record for career high school receiving yards (6,353) and caught 300 passes and scored 75 touchdowns in this time.

Arkansas was considered No. 1 for most of Green-Beckham's recruitment, but his visit to Missouri last weekend changed everything.
