Sweat and Payne, maybe. Allen is legit.
Sweat was playing a new position last year. Dropped into coverage on 40% of his snaps, because he was the best coverage LB on the team (QB rating against him was 70.1), and still got 50 tackles, 7 sacks, 8 TFL, 13 QB hits, 5 QB knockdowns, and 27 QB pressures. He was really good for a rookie who wasn't used properly - he only blitzed on 37 total snaps for the season. For comparison, Shaquil Barrett led the league in sacks last year as a 3-4 OLB and he blitzed on 174 snaps.
