‘Jefferson will turn 27-years-old at the end of this month. He entered the league as fifth round pick out of Maryland in 2016. After two years of playing only nine games for the Seahawks, he started 24 games over the last two seasons, collecting 59 total tackles and 7.5 sacks in his four-year career. In Seattle, the 6-foot-4, 291-pound Jefferson played both defensive tackle and defensive end in their hybrid 4-3/3-4 defense. In Buffalo, he’ll most likely fit in on the interior defensive line.’
