I've been saying Hunter for a long time. I believe what I've been told that it will cost them a WR, probably Jefferson. Hunter is coming off a season-ending torn pec. It's not clear whether or not he's going to be 100% by September, but the odds are very good he would be. The Vikings have already replaced him with Za'Darius Smith.
IMO the real sticking point will be Hunter's contract demands. But if there is a team that can massage the numbers it's the Rams. If Tutu is truly on the rise and they sign OBJ long-term they will be fine giving up Jefferson.
Bruss will be given every opportunity to win the start at RG and I expect him to be the starters. All his flaws look to be technique related and strength all coachable workout issues. Shelton gives them the option at RG but IMO more importantly at LG. Everyone is glossing over Edwards but he is the clear weak link right now in the OL. After two years he's still playing too high, and he still gets bull rushed into the pocket. Edwards was a marginal starting LG last year. I expect him to be allowed to walk next year if he isn't released. They signed Shelton for two years, that's a prove-it type of contract. Everyone expects it to be at RG which it could be. But equally important is the poor play on the left side. So IMO the battles on the OL will be at both OG positions.
I will be surprised if Evans makes this roster. Don't sleep on Jack Snyder this kid has potential. He's better in pass pro than in run blocking but that is largely due to poor technique and he really needs to strengthen. This is the guy I can see taking Evan's roster spot. If he can really impress he could be in play for a starting OG spot next year when Edward leaves.
The Rams are set at OT. Their succession plan is clear. Get one more year out of Havenstein and then get a comp pick for him. Jackson looked solid last year. I think they are looking at him as the starter at RT in 2023. This year he will be their swing OT. Arcuri will be given this year to develop, i.e. correct his issues. He needs a lot of work on this technique, from his feet to his hand play. He dropped in the draft because he was correctly viewed as a 2 year project. So I think they hope he can be their swing OT in 2023.
