MLS does not impose position-specific salary caps. The overall salary budget applies to all players on the roster regardless of whether they play forward, midfielder, defender, or goalkeeper. Teams have full discretion in how they allocate their salary cap across positions.
In practice, attacking players and midfielders tend to command the highest salaries, as Designated Player slots are most commonly used on forwards and creative midfielders who can generate goals and excitement. However, some teams have used DP slots on defenders or goalkeepers when they believe a particular player can be transformative. The flexibility in salary allocation allows each club to build their roster according to their tactical philosophy and competitive needs.
