The NFL salary cap number is expected to take another big leap for the 2018 season. Last year, teams had $168 million to spend. Now a new report from Mike Florio of Pro Football Talk pushes that number closer to $180 million ahead of the upcoming campaign. “PER A SOURCE WITH KNOWLEDGE OF THE SITUATION, THE CAP WILL AT LEAST BE $178 MILLION. IT ALSO COULD EXCEED $179 MILLION,” FLORIO WROTE SUNDAY. Of course, the big reason the salary cap is rising so much right now is that television revenue is coming in like crazy.
