i get this, but do we know that the bonus WAS paid all at once?
The bonus was fully paid to Tannehiil when he resigned, and every year a part of that bonus hit the cap. What remained was 7.8 mil in 2019 as a cap hit, and 5.6 mil in 2020 as a cap hit.
Salary is separate, it hits the cap in addition to the bonus.
Here is the kicker. Tannehill's scheduled salary was 18.8 mil this year with 0 guaranteed money. Therefore, if RT remained on roster, the cap hit in 2019 would be the bonus of 7.8 mil, plus the salary 18.8 mil, which is 26.6 mil total cap hit this year. If they kept him for 2019, they would have to pay him the salary.
If the Dolphins cut Tannehill, he was due no salary, 0 guarantees, because he is cut. They do not have to pay him. The only thing left would be the 7.8 mil cap hit this year, and 5.6 mil next year. But 0 money would be paid.
However, since he was traded, he will have a salary next year, 18.8 million. The Titans were not willing to pay that salary! They were willing to pay only a part of that salary but not the full salary.
So the genius Grier took on a part of that salary, which he did not have to do! Now that part of the salary, which is 5 mil, is an addition to the cap hit. Now the Dolphins are on hook for 7.8 mil bonus, plus the 5 mil salary, which is 12.8 mil. Plus the 5.6 mil bonus hit from 2020 which is accelerated to this year 2019, so the total cap hit is 12.8 + 5.6 which is 18.4 mil total cap hit this year.
The Dolphins took on a larger cap hit than they needed to. They took on a cap hit of 18.4 mil instead of the cap hit of just the bonus 13.4 mil (7.8 + 5.6) and no salary. They added some salary to the cap hit, unnecessarily.
Now, they, the Dolphins say we had to take a larger cap hit than necessary to be ale to trade him and get a fourth round pick, because the Titans did not want to trade otherwise, they did not want to take his full salary and also take a cap hit for that full salary.
So on the flip side, the Dolphins essentially paid 5 mil to get a fourth round pick. The problem is, a fourth round pick makes a total of 2.5 mil over the course of 4 years contract, and of that let's say 1.2 mil is guaranteed.
So now by paying 5 mil for that pick, the Dolphins will essentially pay 6.2 mil guaranteed to a fourth round pick! Instead of 1.2 mil. (net loss cash)
They also increased the cap from 13.4 mil to 18.4 mil. (net loss cap)
And they traded a 6th round pick for a 7th round pick. (net loss draft value)
That's unreal man!
