If her ruling stands, it is still unclear exactly what happens next. The collective bargaining agreement has expired, so how the league would handle free agency, trades and offseason workouts at team headquarters, all of which were banned under the lockout, remains to be seen.
The NFL even argued to Nelson that stopping the lockout would open all 32 teams up to additional antitrust claims simply for working together to solve the labor dispute. Antitrust claims carry triple damages for any harm proven, meaning hundreds of millions of dollars are at stake.
But with appeals expected, the fight seems likely to drag on through the spring and, possibly, into the summer. The closer it gets to August, when training camps and the preseason get into full swing, the more likely it becomes that regular season games will be lost.
