While the Collective Bargaining Agreement might seem like a yawn-inducing topic to many fans, there is probably no single document aside from the NFL rules book that has more impact on the business of the NFL and the roster that fans see on the field every week.
The CBA sets significant parameters on the game, including eligibility, the draft, roster size, salaries, free agency, drug testing, off-season training, franchise tags, and much more. The current CBA is set to expire in about 13 months, and, for a number of reasons, it would be ideal to have the next agreement in place prior to the start of the new league year on March 18th.
