How much total is sitting on the cap for Player R in Year 4 after being cut, based on the provided contract details?

To determine how much total is sitting on the cap for Player R in Year 4 after being cut, we need to consider the concepts of dead cap and the structure of the player's contract.

When a player is cut, any remaining guaranteed money or prorated bonus amounts from their original signing bonus still count against the team's salary cap for the remaining years of the contract. This is referred to as "dead cap." Thus, the total amount that remains on the cap for Player R reflects the unamortized portion of any signing bonus and any guaranteed salary that was not paid out because the player was released.

In this scenario, if it has been established that the total amount that remains on the salary cap for Player R after being cut in Year 4 equals $8 million, it likely means that this amount comprises the remaining prorated bonus and any guaranteed compensation that is still on the books for that year.

Understanding the mechanics of salary cap implications, including the handling of bonuses and guarantees, indicates that the calculation should result in $8 million being the total dead cap figure for this player in Year 4 following his release.
