The problem with the original contract centers on a $2.3 million buyback in the deal for the final season. The deal voids after four years if certain performance levels and team accomplishments are reached, but the Rams can buy back that final year for $2.3 million.
However, new rules in the NFL that are part of the last year with a salary cap mandates that salaries can't increase by more than 30 percent of the first-year total. Brown will be paid $4 million in salary/roster bonus this season, so no increase in future years can be greater than $1.2 million from the previous year.
Brown's salary in 2012 is $5 and $6.2 million in 2013, the final year of the contract. If the buyback is exercised, his final-year compensation would be $8.5 million, an increase of $3.5 million from the year before.
