Gosder Cherilus' contract triggered an obscure salary cap rule, the 50 Percent Down Rule, because his second-year base salary ($1 million in 2014) was less than half his first year base salary ($5.5 million in 2013). The $4.5 million difference between the two salaries is being treated as signing bonus and prorated over his five-year deal ($900,000 annually).
The Raiders didn't get true pay-as-you-go treatment with the five-year, $30 million contract
Austin Howard signed. Since his $7 million roster bonus was only one day after he signed his contract, it's being classified as a signing bonus under the cap and prorated for five years ($1.4 million annually on the cap). At least three days must elapse between a contract's signing and a roster bonus for it to avoid being treated as signing bonus.
The Texans deviated from their usual contract structure with
Brian Cushing's deal. It contains signing and option bonuses. Hefty per-game roster bonuses were required with Cushing ($1.25 million each in 2014-2019) and Schaub ($1 million in each of the past three years) because of injury concerns. Foster also has per-game roster bonuses.
Per-game roster bonuses are a requirement with Green Bay.
Clay Matthews and Rodgers have $500,000 and $600,000 of per-game roster bonuses in their contract extension years.
Cutler has $2.5 million in per-game roster bonuses in the later years of his deal because of his injury history.
