Salary caps also serve the very important purpose of at least tamping down runaway salaries, which hurt everybody but a few players and their agents. Those costs have to be passed onto someone, and that is almost always going to be the end user (the fan).

You could also use the NBA's rookie cap as an example. The cap enables teams to quickly sign players (no holdouts) and makes the players earn their keep and prove they are worth the monster contracts they demand.
