‘Butler was a 2016 first round pick of the Carolina Panthers out of Louisiana Tech when Bills head coach Sean McDermott was the team’s defensive coordinator. New Bills defensive line coach Eric Washington was his defensive coordinator for the past two seasons there. Although he failed to live up to his first round status through his first three years in Carolina, the 6-foot-4, 330 pounder had a breakout year in 2019, collecting six sacks and 32 total tackles. Like Jefferson, Butler projects to play the interior defensive line for the Bills but has the versatility to play outside, especially in a three-down lineman set, where he had much of his success last season in Carolina.’
