49ers free agent history: Ahmad Brooks contract with the team

A week ago, we began taking a look at the 49ers past free agent contracts, beginning with cornerback Carlos Rogers. While no two NFL contracts are alike, that doesn't meant we can't try and learn a little bit from past practices. Today we'll continue our look at free agent contracts with last year's re-signing of Ahmad Brooks.

Brooks signed a six year contract with a max value at around $45 million before free agency began in March 2012. The deal included a $7.5 million signing bonus, yearly $750,000 roster bonuses starting in 2013, and yearly $100,000 workout bonuses beginning in 2012.

Brooks' deal also included escalators and de-escalators that would raise or lower his base salaries based on sack performance. He can void the de-escalators by playing in 93% of defensive snaps, and having the 49ers win 12 regular season games, and reach the NFC Conference Championship game. He failed in two of these requirements this year, as the 49ers went 11-4-1, and he played just under 93% of snaps, clocking in at approximately 92%.

Here is a look at the make-up of his current contract:

2012 Salary - $2.85 million
2012 Base - $750,000

You will find that this deal is similar to the one given in season to NaVorro Bowman. It includes the same signing bonus and roster bonuses, also beginning in year two. The difference is that Bowman will receive a $4 million option bonus in 2013. Just shows you that these deals are basically one year deals, with the fact of guarantees being in there to protect both parties involved.
