It's pretty fitting that one of the first position groups to work out at the combines are offensive linemen. With Grubbs and Andre Gurode potentially leaving in free agency, center Matt Birk mulling retirement and left tackle Bryant McKinnie under contractual control for only one more season, rebuilding the offensive line is arguably the Ravens' top offseason priority.

The good news is that's considered one of the draft's strengths.

"I think there is a lot of flexibility with that interior offensive lineman draft," NFL Network draft guru Mike Mayock said. "I think for the first three rounds, you can get a lot of quality at center or either guard."

Some of the names that have already been connected to the Ravens with the 29th pick include tackle Mike Adams (Ohio State), guards David DeCastro (Stanford), Cordy Glenn (Georgia) and Kevin Zeitler (Wisconsin) and center Peter Konz (Wisconsin).

All five will be at the combine and will undoubtedly be analyzed closely by the Ravens. The Ravens have long subscribed to the "draft the best player available" mantra and that has worked well for them. But at this point, it would be a mild surprise if they used the 29th overall pick on anything but an offensive lineman.

Whittle down their wide receiver options

Despite spending two of their first four picks in last year's draft on wide receivers and then acquiring veteran Lee Evans in a trade, the Ravens remain on the lookout for at least one more explosive receiving threat for Flacco.

Evans, whose end zone drop in the AFC championship loomed every bit as large as kicker Billy Cundiff's miss, is expected to either be released or have his contract restructured. If he is jettisoned, the Ravens figure to have their share of options to replace him and join a group of wide receivers that includes Anquan Boldin, Torrey Smith, Tandon Doss and LaQuan Williams.

The free agent class of wide receivers is filled with No.1 types including Vincent Jackson, Wes Welker, Marques Colston, Dwayne Bowe, Stevie Johnson, DeSean Jackson and Reggie Wayne. There are also productive but less heralded options like Brandon Lloyd, Pierre Garcon, Mario Manningham, Robert Meachem and Laurent Robinson in position to hit free agency.

The Ravens could also address that position in late April as some mock drafts have as many as six receivers going in the first round. Of that group, LSU's Rueben Randle, South Carolina's Alshon Jeffery and Rutgers' Mohamed Sanu could all still be on the board when the Ravens make their first-round selection.
