The skinny: Jack gets all the attention with his dynamic play and occasional action at running back, but Hollins' contributions last year were too good to be overlooked in the shadow of Jack and second-round draft pick Eric Kendricks. It was Hollins who led the team in sacks last year with nine, and even though he made just 31 tackles, his ability to rush the passer will be a key for the Bruins this fall. Jack made 88 stops, second on the team to Kendricks. And while Hollins is going after the quarterbacks, Jack's ability to cover the pass is second to none.
