Whether teams are looking for a pass-rushing 4-3 defensive end or a 3-4 outside linebacker to bring pressure, the options are all over the place, but as usual, will come with hefty price tags.
Dwight Freeney of the Colts was given $14 million last year to see how things would work out in Chuck Pagano's 3-4 scheme, brought in from Baltimore. While Freeney was better-than-average, it is likely that the Colts will be parting ways with one of their best pass rushers in history, just a year after parting ways with Peyton Manning, the man who built downtown Indy.
In regards to Raven Paul Kruger, Ozzie Newsome has said the Ravens will not make the same mistake in 2013 as they did in 2001. By this, he means holding on to the core group that won them a Super Bowl without keeping an eye towards the future. Kruger will be one of the hottest names in free agency and may end up replacing Freeney in Indianapolis, reuniting him with his old defensive coordinator.
Cliff Avril has the Lions in a tough spot. The Lions salary cap is a mess, and Avril won't come on the cheap, after turning down a three-year, $30 million deal last summer. Avril had a down season in 2012, a contract year. He was playing under a franchise tag and was dealing with a back injury. Avril can play in the 4-3 or the 3-4, but when surveying possible suitors, keep a close eye on which teams play on grass surfaces, as Mlive reports.
The Texans would love to keep Connor Barwin, but with all the other needs they face, the money simply is not likely to be there. They need to re-sign Glover Quin, address the interior of their offensive line, and find Matt Schaub more receiving weapons. While Barwin's numbers were down in 2012, that had quite a bit to do with the transcendent play of J.J. Watt, and DC Wade Phillips using Barwin more often dropping into coverage and occupying zones.
As for a few other names garnering consideration:
