Mike Reiss provides a breakdown of the contract and it's definitely a quality deal for both sides, should Browner perform.
Year 1 (2014): $1 million guaranteed, $250k workout bonus, $500k bonus for making the active roster for one day this season, $150k per game active, $1.25 million in playing incentives
Year 2 (2015): $1.9 million base, $2 million roster bonus for league year, $100k per game active, $250k for playing 75% of snaps, $250k for 85% of snaps
Year 3 (2016): $1.9 million base, $2 million roster bonus for league year, $100k per game active, $250k for playing 75% of snaps, $250k for 85% of snaps
The breakdown is $3-$7-$7, for a total of three seasons and $17 million.
What does the structure mean? It's heavily incentive based, so if Browner gets into any more trouble, the Patriots will be safe from cap hits. The reality is the contract is guaranteed for $1 million; if the Patriots want out of the deal, they can cut Browner at any point for minimal damage.
They can release Browner prior to free agency next season and have no dead money.
It's clear how the team copy-and-pasted their terms from 2015 into 2016 that the extra year is the fruit of the negotiations during Browner Watch 2.0.
If Browner plays well, he'll see good money. If he doesn't play well, the Patriots are off the hook. It's a very team-friendly deal.
