Not nearly as much as resigning an OT Rob Haventein who would be an 8 yr veteran of over 100 games started with several SB rings.
No doubt Havenstein in free agency will command sizable dollars, and as we have seen with Corbett during this pre-season free agency period, Edwards will also be in line for a big raise. Corbett may or may not be considered for a secondary role as a Center as was so widely speculated by the Rams last year, Edwards may or may not be considered for a secondary role as a RT, but either way for both these guys, just the thought for them having the flexibility to play a cross-trained swing role boosts their value some on the open market. Both players will be expensive to retain next year.
Hopefully the Rams now have their future starting RG set, and they did draft depth at RT with Arcuri, one spot above Mr. Irrelevent's pick #262. Whether Arcuri stuns us as did Alaric Jackson last year talent-wise is still unproven, although I'll be surprised if he gets past the practice squad in 2022 unless there happens to be an injury. The Rams also acquired a projected OG as a UDFA, that being Jack Snyder, also a likely practice squad developmental player, and whether he'll be cross-trained as a Center is unannounced as yet.
The Rams brought in several UDFA's at various positions, how many actually make the team's 53 roster or practice squad is still very much in question, and there does remain another post camp free agency period if there are any personnel gaps remaining.
