Salary Cap might shoot this down as I am not sure of what all the numbers would be BUT it does not seem that difficult to make the jump to playoffs with a few simple moves.
Get one of the top 2 DE's in FA and overpay (Williams, Avril). If this means not re-signing Stevie and throwing more money at Williams, so be it
Sign the DB who is here today (Routt)
Draft either top top DE/WR/Tackle in first round. If they can get Williams or Avril, I would still go after top DE or OLB
Draft seems to be loaded with WRs that would be great bargains in the 2nd round
I know QB is STILL the missing piece and without that, true contender status will not be reached. For now though, it seems that between the DEs and WRs in both FA and the draft, it lines up perfectly for this team. Fill out the line with 3rd round or others (unless there is an elite tackle there at the 10 spot.
Bottom line, I think this is a VERY important free agency period for this team.
