For Cam Robinson I could see a deal something like...
2 years
$10M signing bonus
$1M salary first year (guaranteed)
$12M salary second year (becomes guaranteed at start of 2026 season)
$1M incentive tied to team sacks allowed
$1M incentive tied to team wins
$1M incentive tied to pro bowl/all pro selection
$1M reporting bonus
$2M in roster bonuses
Up to $4M in playtime bonuses
If he hit all those incentives each year he'd walk away with $21M in the first year between the signing bonus and the incentives, and $22M in the second year between salary and roster bonuses. So it can be reported as a "2 year, up to $43M deal" but in reality could be a 1 year $11M deal if he doesn't work out in year 1 or is replaced. And if he DOES hit all of these incentives, hell, you won't mind paying him! He'd also hit free agency again at the age of 32, and if playing well, would likely get one more nice check.
