Because of the way NFL contracts are structured, there is no easy way to define “highest-paid players.”

Is the player with the highest salary? Well, most top players get a huge chunk of their money in signing bonuses. Is it the highest average annual salary? Well, that considers the entire deal, and most players never see the end of their contracts. Is it who will be paid the most money this year? That would be biased towards players who signed new contracts this year because so much money is in the signing bonus.

Because of this, we have broken up the players by the highest-paid in different categories. Depending on which criteria you use, the answer to “highest-paid” can be entirely different.

Position: Defensive end

Contract: 6 years, $135.0 million

One thing to know: Donald's contract is one of several big deals the Rams have handed out recently, as they take a similar path as the one that led the Seattle Seahawks to the Super Bowl - go all in on players around a young quarterback on a cheap contract.

Position: Quarterback

Contract: 5 years, $135.0 million

Foto: Jimmy GaroppolosourceRobert Reiners/Getty

Position: Quarterback

Contract: 5 years, $137.5 million

One thing to know: Garoppolo is further evidence that one of the best positions to be in as an NFL player is a young, unproven backup with potential, sitting behind an elite starting QB. When that player's rookie deal is up, the original team is not going to overpay for a backup, but other teams will overpay for potential and make the player their starter despite a limited resume. Just ask Brock Osweiler.

Foto: Khalil MacksourceChicago Bears

Position: Linebacker

Contract: 6 years, $141.0 million

At the end of the day, the Raiders chose an above-average quarterback over one of the best defenders in the game.
