The Raiders are looking for help at weakside linebacker and middle linebacker. Caplan hears from teams that Jenkins profiles more as a weakside ‘backer, which is the position he primarily played with the Dolphins.
Jenkins made some noise in 2014 when he had 110 total tackles, 3.5 sacks, two forced fumbles, and one pass defensed. From there, he saw his role gradually decrease. In 2015, he had 71 total tackles and three passes defensed. Last year, Jenkins appeared in nine games and accumulated 29 tackles.
In 2016, Pro Football Focus gave Jenkins the worst grade of any linebacker with enough snaps to qualify for a ranking. His 31.4 score was exceptionally bad, but he had much better showings (76.9; 73.2) in 2014 and 2015.
