Miller's leaving is on him not the Ram FO. They made a legit attempt to sign him but Von's ego to try for a ring with 3 different teams is what made the Bills more attractive. Also, they extended him for more years than the Rams were offering him despite the Ram yearly offer being the same or perhaps slightly more. So Von leaving can't be put on the Ram FO.
It wasn't until this year that Allen could be termed injury prone. When he is healthy he's a very good starting center. The Rams are lucky that they have Shelton who has shown he's a very capable starter in his own right and appears more durable than Allen.
Speaking of durability I have to wonder if they will make a change with Justin Lovett, and Zack Witherspoon and the rest of the strength and conditioning staff. IMO there must be a problem for this many injuries this early in the season.
I said before the season that only injuries could really derail the Rams this year. But I never envisioned how bad it would be this year. If his injury carousel would end this team could make a run even with several starters missing. Kupp is out and he can't be replaced. But it's not like this team doesn't have talent at WR. They finally signed Harris to the 53 roster. If McCutcheon can emerge they will have a solid group of WRs.
With Kupp out and Robinson and Jefferson likely to be their outside starters, it would be a perfect time to move to a 21 personnel offense with Carter as their FB. I've given up caring about Robinson because McCutcheon is playing behind him and is faster. Playing 21 personnel means Stafford will be looking at mostly zone coverages. with Robinson/McCutcheon and Jefferson outside that also would benefit them as well. Now add in Higbee and the RB as dump off options and this offense can morph once again.
McVay needs to revamp his offense. This will be the ultimate test for the boy genius.
