I think the season is lost.
The Rams have come to the point where significant changes are necessary to try and remain competitive. This was bound to occur at some point in the next few years anyway, but all of the injuries, and missed FA signing opportunities appear to have accelerated the process.
I think the Rams need to just ride this out and not rush to sign a mass of lower tier FA's or spend future draft capital to acquire players for one year only to not be able to resign them in the future.
Aaron Donald and Matthew Stafford may only play another year or two, and the Rams need to prepare for that.
It would be a shame to get to the point where AD and Stafford are both gone and the Rams are left to start rebuilding with a bunch of 4th round picks.
