Not necessarily. They have been, but that trend may be fading due to it not working.
Honestly, I'd pay Dak around 37 mil per season if he'd sign a 10 year contract such as Mahomes's. That's the sort of contract we need w/ him so we can play w/ the money to add players. Dak insisting on 4 years is simply selfish. Not to mention stupid.
the trend hasn't changed yet and I doubt if it will...in 2024 the salary cap is expected to go up by 20% or more, which will only help increase the QB salaries. its the most important position in football.
and no, Dak insisting on 4 year contract at most (in 2019) isn't selfish. its business. its market. wentz, goff, wilson all got contracts that end before 2024 and they are going to hit that year as FAs....that was the key to their contracts....and Dak was looking for the same....even Deshan watson contract is designed to be front loaded and him getting out of it in 2024....
Jones could have had Dak for 4 years, with a good average salary, he insisted on 5 year deal. Jones didn't have the upper hand in the market. either Tag him for 32M, and then next year he is FA again....and gets tagged for 38M or some team will give him a contract and you have nothing.....Jones miscalculated and its not the first time. he relented to Zeke with 2 years left on his contract and gave him a ridiculous contract.......he miscalculates all the time often on the wrong side
