Correa has been solid at OLB. He had a good edge hold that allowed Jimmy Smith to come up and make a tackle in game 3 and turned a play inside to Henry in game 1. He had a QH in game 1 that went unrecorded in the Gamebook and altered 2 passes (at least 1 a PD) in game 2. He's done less playmaking than Judon, clearly, but his progress is in line with expectations. One thing we haven't seen much is him dropping to coverage. I'll be looking for that in game 4, when he should get plenty of snaps.
Correa hasn't played many snaps at ILB. In each game, he's played perhaps 3-5 without checking by play. I can't recall a play he made from ILB.
An oddity is that Correa may be competing with Levine/Orr for snaps. Why? Because Pees must make a passing-down choice between the nickel and dime. If the Ravens play more dime, it means CJ Mosley will be the only ILB on the field lined up next to Levine and the front 4 gets very crowded and competitive for snaps. Orr will also play some passing downs in the nickel which makes it more unlikely Correa will see time there.
The best 4-man PR front is probably Suggs, Jernigan, (ZSmith or Judon), Dumervil, but that's also a situation when Urban can wreak havoc with his height or Willie Henry could be disruptive. I'm sure they will find a way to get Correa on the field in more than a special teams role, but don't be shocked if he is inactive some weeks.
Correa's best chance to get on the field is to focus on his edge-setting skills, because the Ravens can use help there:
--Suggs was a HoF run defender when he was last playing regularly, but even in great shape I don't see him playing more than 70% of snaps.
--Dumervil needs to return to a pure situational PR role to maximize value.
--Judon's edge-setting has been mixed in PS.
--ZSmith was supposed to be a good edge setter, but he undershot the mark as a rookie.
--McClellan is the next best after Suggs, but he may occasionally be inactive as he was 3 times last year.
So Correa's best chance for snaps as a rookie may be in a 2-down role.
