I appreciate what Mayfield did and root for him the rest of the way. But unless Stafford is forced to retire he
is the guy in 2023 and 2024. And I think all involved will know his status and intentions by, say, the end of January at the latest. It sounds like he should be alright in the longer term (camp in July).
And while it's clear the Rams should take steps to upgrade the QB2 spot and keeping Mayfield would be great there I don't see how any sort of $10M is viable at all. Wolford and Perkins
combined are making $1.7M. Colt McCoy, just for example, carries a $2.5M cap number this year for ARZ. Could the Rams extend themselves to a $2.5-3M number for a good QB2? Sure. Beyond that I don't see it.
The best thing they can do for Stafford (beyond getting him healthy) is invest some FA money in an OL and draft an OL somewhere in the top 50-70 overall in April.
