http://overthecap.com/nfl-contracts-the-incentive-vs-the-escalator/ Typically both the escalator and incentive are earned in a similar manner. In general these are some type of performance threshold that a player must pass in order to earn a financial reward. For example a team might give the player extra money for playing in a certain percentage of plays or throwing for a certain amount of yards. The big difference comes in the form of actually earning the money. If the performance threshold is tied into an incentive then the player is actually paid when he exceeds the minimum performance level. If I have a $1 million dollar incentive for running for 1000 yards I am going to get a check for meeting that goal. In most cases a team will have their salary cap adjusted for that payment at the end of the year. That will lead to less carryover money or in some cases losses on the following seasons cap. These uncertainties against the salary cap make some teams want to shy away from these incentives because they lose control over the financial planning. Coaches let the players play and (for the most part) they are not going to be stopped because of a cap guy telling them not to play somebody. With an escalator the team does not lose their financial control. An escalator, if earned, simply becomes a raise for the following year. In most cases it is not guaranteed. So from a players perspective they work hard in a prior year to meet a goal but there may be no payoff. In this case most teams will say “there is no chance they can do that again” and because the escalator is not guaranteed will either cut the player or force a paycut. So many releases are due to players seeing their 2013 salaries rise from their play in 2012. This is tough for the player. You can put yourself in their shoes in this case. Imagine if your boss told you that if you sold 100 cars he would give you a raise next year. Then when you do it he tells you he changed his mind and you can either work for your salary from the last year or go find a new job. I’d be pretty frustrated with that and that is what many players, especially mid tier player, experience during the course of their contracts.
