But with the cap being a limit, what would happen if a team spent more than the cap allowed? The short answer is: no team is able to. This is due in most part to the fact that teams have to have all player contracts approved by the league.
"By the first day of the new league year (which this year it's March 2) we have to be in compliance," Xanders said. "Our salary cap has to be under $78.7 million. If you're not in compliance by March 2, you have seven days to be."
And if you're not in compliance after those seven days?

"The last contracts that you signed players to automatically become void and those players become free agents until your charges do come under the cap," Xanders replied. "But that's never happened."
"It's different from the NBA where, if you go over, you have to pay a luxury tax," Beadles echoed. "In the NFL, if you're over the salary cap, then they start making contracts void.
"If you don't decide which players you don't want on your roster, the league will."
