Asa Jackson
Asa Rashaan Webster Jackson (born December 2, 1989) is a former American football cornerback and current football coach. He was drafted by the Baltimore Ravens in the fifth round of the 2012 NFL Draft. He played college football for California Polytechnic State University. College career
Jackson was a four-year starter at California Polytechnic State University, San Luis Obispo, more commonly referred to as Cal Poly. He finished his college career with 137 solo tackles, 199 total tackles, 8 interceptions for 307 yards (ranks first in school history) and 3 touchdowns (ties school record with David Fullerton), 40 pass deflections, 3 forced fumbles, and a single sack for -6 yards. He played in 43 games, and started in 42 of them. In July 2011, he was selected to the preseason Buck Buchanan Award Watch List, among 20 candidates for the Football Championship Subdivision's national Defensive Player of the Year honor, named by The Sports Network. During a 48–14 win over South Dakota State in 2011, Jackson scored on a rare length-of-the-field interception return for a touchdown; although he intercepted the pass about 2 yards deep into his own end zone, NCAA statistics technically record the full return as 100 yards, which equaled the school's deepest return in 43 years. Combined between punt and kickoff returns, Jackson also compiled 936 career return yards on special teams in college. In the final voting for the Buchanan Award announced in January 2012, Jackson received 28 balloting points, including two first-place votes, as New Hampshire's Matt Evans won the award.

Jackson was selected in the fifth round of the 2012 NFL Draft with the 169th overall pick. He is probably most known for returning a punt for a touchdown against the Atlanta Falcons during a preseason NFL game, and then started doing the famous Gangnam Style dance.
