Draft is big for these five teams

These five teams have the most work to do in the upcoming NFL draft.

Baltimore Ravens: The Ravens have taken some hits this offseason. To keep pace in the AFC, they will need another strong draft, something they have an excellent track record of accomplishing. But they don't pick until No. 29 in Round 1.

The Ravens were wise to bring back Matt Birk, but at this point, he is just a short-term fix at center. They lost Ben Grubbs in free agency, and left tackle was a problem area last season -- Bryant McKinnie is very difficult to count on. The offensive line needs to prepare for the future while also getting immediate help on the left side. Peter Konz very well could be Baltimore's first-round pick if he is still available. I would not object to that selection.
