Last week, the 49ers signed cornerback Tramaine Brock to a four-year contract. It was widely reported as a four-year, $14 million deal with $7 million guaranteed.
Per a league source, Brock received a $3.75 million signing bonus. The rest of the guaranteed money comes in the form of future base salaries, most of which are guaranteed for injury only.
In 2014, the first year of the extension, Brock will receive a base salary of $800,000. The full amount is, for now, guaranteed for injury only. On April 1, 2014, it becomes fully guaranteed.
Brock also is eligible for a $130,000 workout bonus, and $320,000 in per-game 46-man roster bonuses.
In 2015, Brock will earn a base salary of $1.85 million, guaranteed for injury only. The $130,000 workout bonus and $320,000 in per-game 46-man roster bonuses also apply.
In 2016, the base salary moves to $2.7 million, $600,000 of which is guaranteed for injury only. Again, the deal has a $130,000 workout bonus and $320,000 in per-game 46-man roster bonuses.
In 2017, Brock receives a non-guaranteed base salary of $3.1 million, along with the $130,000 workout bonus and $320,000 in per-game 46-man roster bonuses.
The cap numbers are $2 million in 2014, $3.05 million in 2015, $3.9 million in 2016, and $4.3 million in 2017.
With quarterback Colin Kaepernick, receiver Michael Crabtree, and linebacker Aldon Smith approaching the time for new deals, it helps the 49ers to have a young starting-caliber corner locked up for four years at relatively reasonable rates.
And if Brock doesn’t thrive in 2014 as a full-time starter, the 49ers can pull the plug on the deal, cutting Brock off at roughly $5 million of total payout with no further obligation.
