How big is his slice of pie?
When you look at the salary cap and quarterback contracts, you essentially have to look at how much of the total cap is the player making and compare it to the market and their impact on the team.
Let’s start with the first half of that equation.
So what that means is that the Titans think that next year he is worth about 15% of their cap. That makes complete sense when you look at what he did last year.
I get that Derrick Henry was good, but do you know how many times the Titans have gone to the AFC Championship game since Derrick Henry has been there? Once. Do you know how 100+ yard rushing games Henry had before Tannehill started? 5 out of 53 games played.
I’m not trying to take anything away from Henry, but what I am saying is that Tannehill gave the Titans a counter-punch to attack defenses with when they loaded the box and the team thrived with that combination.
Assuming any QB could come in and do that as well as Tannehill did is ridiculous and you should be willing to pay 15% of your cap space (when you know that percentage will get smaller over time) when a player makes such a big impact on year team.
