From espn:
'To justify his price tag, Kruger will need to produce as an every-down linebacker in Cleveland; remember that the Ravens used Kruger on only 22 defensive snaps in the Super Bowl because they preferred other players who were better run-stoppers in their base defense.
So, are the Ravens totally lost in the wilderness having traded Boldin for cap space that they didn't use? Of course not. They have Ozzie Newsome. He's good at this stuff. Chill. Baltimore made one very Ravens-esque signing on Tuesday, bringing in versatile Giants lineman Chris Canty on a three-year deal for just $8 million, with a mere $2.8 million guaranteed. Canty is versatile and experienced with both 3-4 and 4-3 schemes, and he still has enough athleticism to play end or tackle in either scenario. He can be the new Trevor Pryce for the Ravens.
As for the linebacker issue? There are still linebackers out there, and if the Ravens didn't think Ellerbe was worth paying like a franchise inside linebacker, they would know best. The Ravens could opt to go after the versatile Dansby as a short-term solution. One other fascinating option that probably won't happen: What if the Ravens outbid the Bears for Brian Urlacher, who has quietly come to an impasse with his only professional organization? It makes a bit of sense for both sides, although probably not enough for a deal to actually happen.'
