– According to the Boston Herald and Patriots’ beat writer Mike Reiss, guard Logan Mankins has requested a trade in wake of his current contract situation. Says Makins: “I don’t need to be here anymore. This is about principle with me and keeping your word and how you treat people.”

The Patriots aren’t big on handing out big contracts to guards (or anyone not named Tom Brady for that matter), but it’ll be interesting to see what approach they take now that Mankins has demanded a trade.

– The NFL has suspended Titans linebacker Gerald McRath four games for violating the league’s policy on performance-enhancing drugs. He was expected to start this season after seeing extensive action last year as a rookie, but now it appears that David Thornton’s job is safe.

Speaking of the Titans, Chris Johnson continues to stay away from mini-camp in hopes that the team will give him a new contract. A resolution doesn’t appear to be in sight, as the Titans wants him to play on his current deal, which still has three years remaining on it. Of course if CJ decides to holdout through training camp, Tennessee could be forced to pony up. Johnson is without a doubt their most productive player.

– Elvis Dumervil signed his one-year, $3.168 million tender with the Broncos on Monday. The Denver Post’s Lindsay Jones writes that the two parties will continue to work on a long-term deal, which Dumervil deserves in wake of his performance last season.

– The Vikings re-signed restricted free agent Ray Edwards to a one-year, $2.521 million deal. The defensive end had threatened last month to hold out, but apparently that was just a ploy in hopes of receiving long-term contract. Edwards recorded 51 tackles and 8.5 sacks last season.

As part of our 2010 NFL Draft coverage, I will be breaking down positional needs for all 32 teams, starting in reverse alphabetical order. Next up are the Tennessee Titans. Check out other team needs by clicking here.

1. Defensive End
It’s unlikely that the Titans will bring back Kyle Vanden Bosch (who is injury prone and in decline) and Jevon Kearse (also in decline) next season, making the defensive end spot opposite William Hayes a top priority. There’s a very slim chance that the team will be able to woo free agent Julius Peppers to Tennessee, so the Titans might use the No. 16 spot in the first round to take a DE prospect like South Florida’s Jason Pierre-Paul.

2. Cornerback
Nick Harper will be 36 in September, is coming off shoulder surgery and struggled mightily in coverage in 2009. He’s also a free agent and there’s little to no chance that the Titans will re-sign him for next season. That means the cornerback spot opposite Cortland Finnegan is a major hole, although the Titans are in a tough spot at No. 16 in the first round because Florida’s Joe Haden will likely be off the board and Florida State’s Patrick Robinson would be a reach there. They could sign on a free agent like Leigh Bodden (Patriots), although that all depends on how much Bud Adams is willing to spend this offeason.

3. Linebacker
The Titans appear ready to move on from veteran linebackers Keith Bulluck and David Thornton and now have to determine whether or not Gerald McRath and Colin Allred are starters. If the team does view the pair as solid replacements for Bulluck and Thornton, then the Titans can concentrate on other positions, such as the defensive line, cornerback and backup running back. If not, then outside linebacker becomes one of the biggest needs of the offseason, especially from a depth perspective.

If the Titans don’t re-sign Kevin Mawae this offseason, then center also becomes a need for next season.
