Address all position in FA that are a glaring weakness. Then build depth through the draft. The draft should be where you build depth at key positions., not search for starters. If those starters break through, than that's awesome, you did a great job scouting. But I say go get a WR, TE, QB, G, LB, CB in Free Agency. Bring in some players who have been on Playoff Teams to help bring about a change in attitude in the locker room.
We need a culture change. FA's who have been on winning teams and were leaders are a great way to bring about an attitude change on this team.
