Looks like the contract is 10 years, more than $500 million. I know they can shift money around etc. But you cannot have a contract that size and not have humongous cap hits. There's just no way. KC is going to have to make huge sacrifices elsewhere to accommodate this contract. Mahomes is already the best player in the world. I don't know how much better he can realistically get. So it's not like they'll be adding a great player at QB in the years to come. He's already here and he's already basically at his peak. So the only thing really they can do is go down from here roster-wise.
With the Pats...Brady went from a nice young QB to the GOAT. But it took time. His contract grew, but the talent and production grew too, which helped compensate for the fact that his increased salary meant making cuts elsewhere. But with Mahomes...honestly, how much better can he get to compensate for the fact that he will be making on average more than 12 times what he was, that his salary is going from $4 million up to $50 million a year?
Just as a reminder...
2018: 66.0%, 5,097 yds, 8.8 y/a, 50 td, 12 int, 113.8 rating, MVP
2019: 65.9%, 4,031 yds, 8.3 y/a, 26 td, 5 int, 105.3 rating, SB champ
Where can he improve? Maybe completion percentage. But keep in mind that unlike Brees, Mahomes airs it out constantly. It's what makes them so dangerous. He's throwing lower-percentage passes in general compared to Brees. He's not going to complete 70% of his passes throwing deep. His average intended air yards per pass was 8.6. Brady's was 7.6. Brees' was 6.7. It's really difficult to complete 70% of your passes throwing the ball as deep on average as Mahomes does. But maybe that goes up a tick. He doesn't throw many interceptions, but maybe he gets a little better at that. He already runs well - 272 and 218 rushing yards the past two seasons (4.5 and 5.1 averages), respectively. He's not a "running QB" like Jackson or Cam. But he's a great athlete who can run when necessary.
So I don't really see how he can get much better. KC already averages ungodly numbers of points and yards with him at the helm. I mean, during last year's playoffs they scored 51, 35, and 31 points, for an average of 39 a game. In the playoffs. I don't know how much better he or they can get offensively.
