A player’s Cap number is usually comprised of several parts. First the player has what is known as his P5 Salary (as in Paragraph 5 of the standard NFL contract). This is what is otherwise referred to as a player’s yearly base salary. Players also often receive bonuses – of different varieties – that will also count as part of his Salary Cap number. The most common types of bonuses are Signing Bonuses, Option Bonuses and Roster Bonuses. The 3rd common component of a player’s Cap number is Incentives (see explanation below).
