If you don’t pay top QB money, you won’t have one that’s worth a hill of beans. You guys that think you can win a championship with a cheap QB are kidding yourselves. They may not win games single-handedly, but they influence the outcome of games, especially championships more than any other player. The difference in last years Super Bowl was Patrick Mahomes. Purdy had an opportunity to close out the game and couldn’t do it and Mahomes did. Mahomes is the main reason KC has won back-to-back championships. He was able to overcome their deficiencies at WR. That position cost them some games last season.
Sure and if we had Mahomes on the Cowboys it's a non discussion. For most QBs in the league I would be careful though. Not only is Mahomes the best QB in football, he also took a very team friendly 10 year deal. Him and Brady are the only big money QBs to consistently make it to the super bowl. Brady also got his money in his 2010 deal ($18M AAV) and then left money on the table with each additional extension ($13M AAV in 2013, 9M AAV in 2015, $20M in 2016, $15M in 2018, $23M in 2019, $25M in 2020, $15M in 2022. Outside of those two who played on mostly team friendly deals the evidence is pretty split:
Mahomes v Purdy - 1 big money, 1 rookie deal
Mahomes v Hurts - 1 big money, 1 rookie deal
Stafford v Burrow - 1 big money, 1 rookie deal
Mahomes v Brady - 1 big money, 1 rookie deal
Mahomes v Jimmy G - 1 big money, 1 rookie deal
Brady V Foles - 1 medium money, 1 cheap deal
Brady V Ryan - 1 medium money, 1 big money
Manning V Newton - Both big money
Brady V Wilson - 1 medium money, 1 rookie deal
Wilson V Manning - 1 big money, 1 rookie deal
Flaco V Kaepernick - both on rookie deals
If you go back further than that I think it starts to support a model where you need to pay your QB as the super bowls and CCGs were dominated by the same guys (Brady, Brees, Rodgers, Big Ben, Warner, both Mannings, etc.) however in 2011 no QB took up more than 14% of the cap at signing. Fast forward to today and you have 15QBs currently taking up more than that and the list about to grow, with 11 of those north of 20% going up to the leader of Joe Burrow at 24.5%.
It's simply a different world in the 2020s than we lived in the previous decades. If the contracts were simply exploding in terms of an amount proportionate to the explosion of the salary cap I would be with you 100% in you need to just resign your guy if he is at least an above average starter. The fact that we are seeing such a drastic increase in % of the cap going to the QB position I think makes it incredibly more difficult to build a true contender, especially one that isnt in a Rams type of all in on one year model. For that reason I would be very selective about which QBs I would give extensions to.
