I haven't seen the contract specifics, but I'm assuming we are paying MVS the minimum, which is interesting given that he had a fully guaranteed minimum salary (+ small signing bonus) with the Bills.
The Bills will get some cap/cash relief from the signing, but MVS would be taking on injury risk without any additional compensation in 2024. I doubt he signed with us as a contender, he must see enough opportunity to get some decent film on tape to make the risk/reward worth it.
