A lot of Razorback fans are hoping new defensive coaches Paul Haynes and Taver Johnson will be able to produce a stronger defense on the field, but, along with the defensive-minded John L. Smith at the helm, we're already seeing a renewed focus on defensive recruiting. (Bravo!) Less than a week after defensive back Carroll Washington committed to the Hogs, it is being widely reported the Razorbacks received their 13th commitment (7th defensive commit) from linebacker Marcus Robinson.

Robinson, a prospect out of Memphis, is generally considered a 3-star recruit and has a pretty nice offer sheet. He chose Arkansas over several BCS schools, including Clemson, Vanderbilt, Ole Miss, Mississippi State, Illinois, and North Carolina.

Now that Arkansas has 13 commitments, the class is officially halfway full if every commitment sticks. What do you think of it so far?
