Tom Pelissero:Rams Give Matthew Stafford Permission to Speak with Other Teams

Stafford is considerably cheaper. In 2025, he’s owed $27m vs $40m for Carr. He’s also due $58m over the next two years compared to $90m for Carr.

He may want some new money if he gets traded, but I don’t think any team will give him $90m+ for two years.
Stafford's option bonuses come with him to the new team if he's traded, so his cap number is $33.5m for 2025 and $37.5 in 2026. If he's cut by the Rams, I believe they have to eat those option bonuses on top of his prorated bonuses as dead money. That gives them an incentive to get a trade done rather than cut him.
