History Says Patrick Mahomes and Dak Prescott Shouldn't Sign Record-Setting Contracts
By Michael Luciano

After Patrick Mahomes won the Super Bowl in dramatic fashion, while Dak Prescott set new career highs in several categories, the pair of star quarterbacks are looking for major paydays in the near future.
They have both outplayed their pitiful current contracts, but both the Chiefs and Cowboys should pause before breaking the bank, as the QB with the highest salary cap hit in the league has had literally no postseason success over the last decade.
Mahomes, Prescott and Brady may deserve top-tier contracts, but what do those contracts do to their teams?

Well ... the QB with the highest salary cap hit in the NFL has missed the playoffs in 8 of the last 10 seasons — and the only 2 to make it lost their first playoff game. pic.twitter.com/QjfsukXZmK
Every non-Manning on this list has missed the playoffs, and none of them won a playoff game.
While some of these contracts are hilarious outliers (Donovan McNabb's cap hit on the Redskins not being surpassed until Jimmy Garoppolo's contract in 2018, Mark Sanchez costing more than any QB in the league), the trend is worrisome for the Chiefs and Cowboys.
Unless they keep acing the draft and drafting stars to play on rookie contracts, that could make it hard for either Mahomes or Prescott to sustain success.
No player has ever had the contract leverage Mahomes has this offseason. The Chiefs have to give him whatever he wants.

There is not a single soul that has a functioning brain that believes Mahomes shouldn't be the highest-paid quarterback in the league based on his talent and performance on the job. Likewise, Prescott should get a nice new deal. However, his contract is going to force deep Kansas City and Dallas rosters to jettison some of their key pieces, and both Jerry Jones and Brett Veach need to be ok with that reality. Only time will tell how things end up playing out in the Big D and KC.
