I've asked this question of the forum before without reply, but would you sacrifice Littleton should someone like Scherff become available in free agency ? The Rams have been stockpiling young ILB's, so i'm guessing there may be some reluctance to handing out a huge payday for Littleton at a position where Wade Phillips has traditionally not been inclined to do so.
Zuerlein has been hurting himself recently with missed field goal attempts, it has to affect that next contract he's hoping to sign.
Morgan Fox is an RFA, so his return is pretty much guaranteed, Christian is replaceable.
Ramsey, Kupp, Everett & JJ3 won't become free agents until after the 2020 season, and while their extensions are likely to be done in 2020, they won't take effect until 2021 when our overall CAP situation is improved. jmo.
