Says ESPN:
Carson Wentz | Signed through: 2024. Tier: Locked-in vet | Ranking in tier: No. 4
Contract: Four-year, $128 million extension signed in June 2019, including $66.5 million fully guaranteed at signing.
Wentz’s contract structure is built on staggered roster bonuses that were designed to help the Eagles navigate 2019 and 2020 salary cap issues. He’s basically getting $30 million this year and $25.4 million fully guaranteed in 2021.
None of his salary is guaranteed beyond 2021, though a $15 million 2022 roster bonus becomes fully guaranteed if he’s still on the team in March of 2021. (It’s also worth noting, given Wentz’s history, that his 2022 salary is currently guaranteed for injury.)
The remaining proration of the bonuses means the Eagles would incur a dead-money charge of about $39.5 million if they decided to move on from Wentz in the 2022 offseason.
That’s a whopper of a cap hit, which likely means Wentz keeps playing on this contract for three more years, even though the Eagles aren’t contractually married to him for any longer than that.
