You shouldn't look at the OL as individual players. Look at the OL as a unit and what do you see? An OL that can't stay healthy, and that is an abberation in the NFL, where the entire unit is constantly getting hurt. Maybe that is why Carberry is gone and they hired an OL coach who actually played OL for 9 years in the NFL. What that means is that Wendell can look at not only how they play, i.e. technique but how they train. Let's see how this unit performs and what their injury rate is this year. Personally I'd be surprised if it didn't improve.
When Noteboom is healthy he's an outstanding LT. Remember Alaric Jackson has shown he can play LT as well. He's a restricted FA next year meaning the Rams control his fate. If they choose to move on from Noteboom then they can put a first round tender on Jackson. The Rams have options. Why not move on from Noteboom now? Because he's that good that's why. Give him as well as Allen one more year to prove they can play injury free. They can then renegotiate the contract if they feel confident or they can move on.
The reason I've been saying that Jackson is the logical successor to Havenstein is not only is he better but simply because I knew Jackson was a RFA. They could either negotiate a contract or tender him. Either way they control his rights at least one more year.
Bottom line I don't see any real downside here. The Rams were for some reason IMO forced to advance their plans by a year. I think Jalen forced their hand with his demand for a new contract or be traded. If Noteboom is indeed 100% by September that will be very good news for Stafford.
