Provided Flacco isn't a Raven in 2019 - When will we feel his cap relief? 2020 earliest right? And I know sometimes with a lot of dead money, they will split it over two seasons, so possibly 20201?
$16M in remaining bonuses needs to be accounted for if he's not on the 2019 roster.
If traded, it all goes on 2019 cap.
If released, it can either all go on 2019 if they choose or they can split it $8M in 2019 and $8M in 2020 by making him a post-June 1 designee. They wouldn't gain any cap relief at all until June 1, though, so that second $8M and his $18.5M 2019 salary will still be on the books when free agency opens in March 2019 in the post-June 1 case.
