Fletcher Cox (3.5 sacks, 3.5 TFL, 1 PBU, 3 qb hurries one FR for TD)
Denico Autry (1 sack, 2 TFL, 3 PBU, 3 qb hurries)
Kyle Love (1 sack, 1 TFL, 4 qb hurries)
Pernell McPhee (4 sacks, 4 TFL, 9 qb hurries!)
Preston Smith (4.5 sacks, 6 TFL, 2 PBU, 8 QB hurries)
Chris Jones (3.5 sacks, 4.5 TFL, 7 qb hurries, 2 PBU, 1 INT)
Benardrick McKinney (37 tackles, 2 sacks, 6 TFL, 4 qb hurries)
K.J. Wright (42 Tkls, .5 TFL, 1 qb hurry, 1 PBU)
Darius Slay (25 tkls, 1 TFL, 3 INT, 8 PBU)

If you had to pick 3 that were the most dominant right now, who would it be?

I'm going Cox, Smith, and Slay. Although McPhee and McKinney are right there.
