Tar Heels sign JuCo defensive tackle Williams

North Carolina is adding some depth to its defensive line for 2011. On Thursday, the Tar Heels announced that Sylvester Williams, a 6-foot-3, 320-pound defensive tackle from Coffeyville (Kan.) Junior College has signed a national letter of intent and will enroll in January. He will have two years of eligibility remaining.

Williams did not begin playing organized football until his senior season at Jefferson City (Mo.) High School, according to UNC. He enrolled at Coffeyville in January, 2009. He earned first-team all-conference and first-team all-region honors in 2010 and was an honorable-mention NJCAA All-America.

Last season he had 52 tackles, including 12.5 for a loss and two sacks, two pass break-ups, a forced fumble, and five blocked kicks.
