One additional detail that I've seen reported now is that only the first two years are guaranteed. So what we know is that signing bonus + 1st year + 2nd year is between $46-ish and $55 million. The only real remaining question is how much of the cap hit they are pushing into years 3+ by making making part of that guaranteed money in a signing bonus. The more of the cap hit the team is willing to absorb now, the easier it would be to part ways later, but considering that the Dolphins are relatively strapped for cap space now, odds are a good portion is a signing bonus and thus prorated over the life of the contract.
With the new information we can make a stab at a contract, remembering that Howard has already prorated bonus money of $2.66 million in 2022 and 2023 along with $1.26 in 2024.
Given the constraints we have (providing they are accurate) and trying to make sure the year 3 salary doesn't crater (players generally don't like their salary paid to do that with the exception of signing bonuses), there actually isn't too much flexibility. Something like the following would be my guess:
Signing bonus: $39 million
| Year | Salary | Cap hit | Dead money |
| 2022 | $2.0 | $12.5 | $54.6 |
| 2023 | $7.0 | $17.5 | $37.11 |
| 2024 | $7.0 | $16.1 | $24.7 |
| 2025 | $17.5 | $25.3 | $16.9 |
| 2026 | $17.5 | $25.3 | $9.1 |
Salary in this context includes roster bonuses. For veterans, base salary becomes guaranteed week 1 of the season (but paid out in installments each week of the season), whereas a roster bonus is paid out early in the league year (not always first day, though). There has been a bit of a shift towards guaranteeing some portion of the base salary early in the league year instead of giving it as a roster bonus, which only benefits the team since that money would not be paid out in the event of a suspension.
Finally, some reports mention an additional $5 million in possible bonuses. Some of that might be workout and per game bonuses, but the Dolphins haven't done that much under Grier. Some could also be attributable to performance-based bonuses (say a million a year if Howard gets a certain number of INTs). Or it could be a 3rd year bonus to pad out the money paid that year, particularly if the signing bonus is larger.
