With a few notable exceptions (Manning/Bailey) there are a number of players who won't have many years ahead of them based on age or waning skills - if they ever actually had the level required for a SB team.
If I refer to those that will be 30 plus next season, who should go and who should stay. They are:
C - Koppen - Walton will be back, CJ Davis is adequate cover, Blake must have been bought for a reason and Saulsberry (from the PS) could step up - NO additions required
RG - Kuper is proving to be injury prone and an upgrade on Ramirez would be good - I think BARRET JONES (6'5" / 320 out of Alabama should be our first round draft choice.
DT - Vickerson, Bannan, Warren (if ever fit!) can't go on forever and although we have Siliga and Unrein - I think SYLVESTER WILLIAMS (6'4" / 320 out of North Carolina) should be our second round draft choice.
ILB - Brooking will be 38 and Johnson hasn't set the world on fire - I think SHAYNE SKOV (6'3" / 242 out of Stanford) should be our third round choice and may become an immediate starter.
OLB - I'd have got rid of DJ Williams for a number of issues well before now, but I think in Woodyard and Trevathan I think we have enough cover not to rush into the trade market.
FS - Leonard has been good cover, but I think our fourth round choice should be ZEKE MOTTA (6'2" / 215 out of Notre Dame) who could team up with his old college partner:
SS - Adams has also done a reasonable job and kept Bruton to limited time, BUT Motta's Notre Dame college partner BLAKE GIDEON is on our practice squad would be an ideal replacement for him.
I accept the older guys may have a few miles left in them, we could use FA and that the FO might see other requirements and trade up or down, but think these four would be valuable additions.
