Ramsey's extension won't take effect until the 2021 season even if he signs it today.
He's already on the books for 2020 for just over $13M - the 5th year option on his rookie contract. When he does finally agree to terms on an extension there's virtually no chance that it will have much - if any - effect on his 2020 cap hit. It's simply the way the Rams have operated for years and to expect anything else is simply betting against overwhelming odds.
See the contracts that Goff, Gurley, and Havs signed as just a few recent examples.
