Clemson's defensive line wreaked havoc on offenses in 2017, and it's coming back for more in 2018. Christian Wilkins, a 6-foot-4, 300-pound defensive tackle, announced on Monday that he'll be returning for his senior season with the Tigers, ensuring that Clemson will have three returning first-team All-Americans among its front four in 2018. First-team All-American DEs Clelin Ferrell and Austin Bryant announced on Saturday that they'll be staying in school for the 2018 campaign, and DT Dexter Lawrence will return as one of the top players at his position, too.
