The San Francisco 49ers signed tight end Garrett Celek to a four-year contract extension earlier this week, and further details are available. Ian Rapoport initially reported the deal was worth $14 million, with "nearly" $5 million in guaranteed money. We can now add the base salaries to our understanding of the contract.
According to the NFLPA, Celek will earn base salaries of $1 million in 2016, $1.55 million in 2017, $1.65 million in 2018, and $1.9 million in 2019. More than likely, the $5 million in guaranteed money includes his $1 million salary this year, and then his signing bonus. It is possible that "guaranteed" includes future salary, but my guess is it is primarily 2016 salary and signing bonus.
The base salaries add up to $6.1 million. For arguments sake, let's say the guaranteed money includes the $1 million base salary and a $4 million signing bonus. That would leave us accounting for approximately $3.9 million of his $14 million deal. That would include some roster and workout bonuses, and potentially various incentives. Using those various hypothetical numbers, we'd be looking at annual cap hits of $3 million in 2016, $3.55 million in 2017, $3.65 million in 2018, and $3.9 million in 2019. Again, those are entirely hypothetical, without knowing what incentives are unlikely to be earned, and without knowing the exact specifics of the signing bonus.
