He spent last season making the transition to 3-4 OLB & had 5.5 sacks while rotating with 1st round pick Barkevious Mingo on the right side. He also missed 3 games in 2013, thus further hampering his production. Former Browns DC Ray Horton said he could play on both sides in the 3-4...and he initially was working on the left side, before switching back to the right side. Kruger starts on the left side.
As mentioned, he's been rotating with Mingo since they went to the 3-4. Additionally, he recently sustained a foot injury that they initially thought would end his season, but it turned out he didn't need surgery & returned. He's not benched, but rather on a snap count in a rotation with Mingo. And he has been one of the few players for them that's been decent vs. the run, as the team as a whole has struggled.
Personally, I see producing on really bad teams as a positive. Despite talent lacking around him...he had 55 tackles, 8.5 sacks, and 5 forced fumbles while starting on the right side as a rookie. In his 2nd season, he had 55 tackles & 7 sacks. In other words, his production wasn't coming on the coat tails of others.
I agree about Rosenhaus. And while I don't think he'll come 'cheap'...he may not command what some of the other pass rushers might. Injuries & a position change have indeed hampered his production over the past 2 seasons, and that may factor into things. In addition to contracts received by guys like Avril, Bennett, etc...who had more production on their resumes.
As far as Cleveland is concerned...not sure he's ever been in their long-term plans. While the Browns did have initial contract talks, they paid Kruger quite a bit of money to play LOLB...and drafted Barkevious Mingo with the 6th overall pick in 2013 to play on the right side. Not to mention...he was more productive in the 4-3 at DE.
In the end...he's not a guy I'd wrap up significant/elite cap money in. Then again, I could say that about pretty much all of the free agent pass rushers. However, If a decent contract could be reached...I think he & Lawrence could potentially be a solid/young tandem at RDE.
