A settlement being discussed in an antitrust lawsuit against the NCAA and major college conferences could cost billions and pave the way for a compensation model for college athletes.

An agreement has not been finalized and many questions remain unanswered. It is also unclear if new rules could withstand further legal scrutiny, but it appears college sports is heading down a revolutionary path with at least some schools directly paying athletes to participate. Here’s what is known and what still needs to be figured out:

THE CASE

House vs. NCAA is a class-action federal lawsuit seeking damages for athletes who were denied the opportunity to earn money from use of their name, image or likeness going back to 2016. The plaintiffs, including former Arizona State swimmer Grant House, are also asking the court to rule that NIL compensation should include billions of dollars in media rights fees that go to the NCAA and the wealthiest conferences (Big Ten, Big 12, Atlantic Coast and Southeastern), mostly for football and basketball.
