Who knows what went on behind closed doors. Here is my guess. They signed him to a 3 year extension before last season with little reason to do so. But only this year has effective guarantees, meaning after 2025 they could cut him, escaping roughly $20M/year for a 31/32 year old cornerback For that season). Them they were bad last year. Really bad. Then Hill started getting noisy. And (just guessing) Ramsey saw the future where they cut him after this season and he was an aging corner and stuck getting aging/somewhat difficult cornerback contracts and he asked/demanded for more guarantees. The dolphins recognized this would be folly for where they were as an organization, and thus an ‘agreement’ was reached.
what Ramsey will accept and what will happen will be interesting, but he has little leverage. After this year teams will look at the exact same things the dolphins did and, in my opinion, he will have to face reality, as all aging stars must. I believe the only negotiation for this year (where the money is guaranteed) will be a balance for draft choice and money. A 3rd rounder and dolphins eating half the money (his $9M option bonus due week 1, for example; they already paid his $4M roster bonus) sounds good to me.
