Starters (weak side to strong side)—Vontaze Burfict, Rey Maualuga, Vincent Rey
Reserves—Jayson DiManche, Emmanuel Lamur, Brandon Joiner, J.K Schaffer, Marquis Flowers
Vontaze Burfict, a perennial all-star in this league, is going to start for the Bengals as long as they can afford him. He led the NFL in tackles in 2013 with a whopping 171.
Rey Maualuga, a player who is not nearly as effective, seems to also be a lock as a starter, despite his questionable coverage prowess. Admittedly, his attack against the pass seemed to improve in 2013 after a disastrous 2012 showing.
That leaves the strong side, which is left empty with James Harrison's departure. The favorite to take over has to be Vincent Rey, who had his best showing in his short career last season. Rey was incredible filling in when Harrison and Maualuga were hurt, totaling 57 tackles, four sacks, a forced fumble, a fumble recovery and two interceptions.
He's more suited and used to the MLB position, but I see no issues letting him play on the strong side. He certainly is capable of covering the middle of the field and blitzing, both of which are huge requirements for linebackers.
Don't sleep on DiManche or Lamur, however. Lamur, an undrafted free agent in 2012 showed a lot of talent during training camps and the preseason that year, but he missed 2013 with an injury. Meanwhile, DiManche showed promise filling in for injuries as well.
Overall, these guys make up an "A-" linebacking corps, and I expect it'll be an "A+" by the end of the year.
