Texas star linebacker Malik Jefferson has declared for the 2018 NFL Draft. The five-star recruit out of Mesquite Poteet announced his decision Sunday via The Players Tribune, tweeting a video explaining his decision. "This is one of those decisions I have to make as a young man," Jefferson says in the video. "It's been a long process and a very difficult decision by leaving my teammates. They supported me in everything I did, but it's a dream of mine and I appreciate them for all their support." Jefferson played and started in all 12 of the Longhorns' games this season before missing their Texas Bowl win with turf toe. His 110 tackles (79 solo), 10 tackles for loss and four sacks merited co-Big 12 defensive player of the year honors. Jefferson was also named first-team All-Big 12, second-team All-American and a semifinalist for the 2017 Butkus Award recognizing the nation's best linebacker.
