Quarterback was one area of concern for coach Brad Childress and Co. and the hope is that the addition of Sage Rosenfels can create some competition for Tarvaris Jackson.

TEAM NEEDS/OFFSEASON STRATEGY

The Vikings elected to retain fullback Naufahu Tahi by matching the one-year, $1.4 million offer sheet the restricted free agent had signed with the Cincinnati Bengals.

That came shortly after the Vikings made one of their biggest moves of the offseason when they signed cornerback Cedric Griffin to a five-year contract extension. Griffin had a year left on his rookie contract.

The Vikings have added only two free agents from outside the organization, signing cornerback Karl Paymah and wide receiver Glenn Holt to one-year contracts. Paymah will battle for a job in the nickel defense and Holt likely will see the majority of his time on kickoff returns.

The biggest outside addition was the Vikings' trade with Houston for Rosenfels. That trade cost the Vikings a fourth-round pick in this year's draft. The team still will have six picks in the draft, including two in the seventh but none in the fourth or sixth rounds.

MEDICAL WATCH: Cornerback Charles Gordon (left ankle), right guard Anthony Herrera (shoulder) and right tackle Artis Hicks (triceps) are among the players who are expected to be limited when the Vikings begin Organized Team Activities in May.

FRANCHISE PLAYER: None.

TRANSITION PLAYER: None.

UNRESTRICTED FREE AGENTS

--DT Kenderick Allen spent the season on injured reserve after injuring his right wrist during the Vikings' preseason opener. It would not be surprising if he does not return.

--S Michael Boulware spent the year on injured reserve after suffering a broken wrist during the preseason. Could return in a special-teams role in 2009.

--LB Napoleon Harris signed early in the regular season after middle linebacker E.J. Henderson was lost because of a foot injury. Harris, who had been let go by Kansas City before joining the Vikings, likely will be allowed to leave.

--OT Marcus Johnson, the lone remaining member of the Vikings' 2005 draft class, was a non-factor in 2008 and almost certainly won't be back.

--LB Dontarrious Thomas signed during the season to add depth after Henderson was injured. The Vikings probably won't try to bring him back.

--DT Ellis Wyms proved to be a valuable backup to 3-technique Kevin Williams. He has expressed a desire to return.

RESTRICTED FREE AGENTS

--DT Fred Evans (tendered at $1.545M with second-round pick as compensation) was the primary backup to Pat Williams at nose tackle. Evans is considered to be an ascending player.

EXCLUSIVE RIGHS FREE AGENTS: None.
