Darrelle Revis will be playing again, and he’ll essentially be playing for free. With $6 million in guaranteed salary paid to him this year by the Jets, and with the Jets eligible for a dollar-for-dollar offset, Revis will have no net earnings over the next six weeks — unless the Chiefs are paying him more than $1 million per week. The Jets also may argue that they should receive credit for any money he makes in the postseason. The per-game playoff share isn’t gigantic, however, maxing out at $107,000 last year for winning the Super Bowl.
