The 18-game NFL regular season is coming. It’s a matter of time, money, reorganization — and some inevitable hand grenades tossed across the negotiating table.

It's the same as it was in 2008, when NFL team owners triggered an early opt-out clause in the collective bargaining agreement. Same as it was when the league tried in vain to get a 17th game added into the 2011 CBA (the current CBA doesn't contain an opt-out clause). And same as it was nine years later, when players finally agreed to expand the schedule, negotiating a tradeoff for a larger share of revenue, a more accessible pension, a handful of veteran-friendly contract and franchise and transition tagging enhancements, and changes to the league’s drug-testing and suspension policies.
