Sunday night's Kansas City Chiefs-Denver Broncos game was flexed into prime time, despite the fact that CBS initially protected it. Get ready for far more flexing of games on Sundays next season.

The league is creating a new weekly system of cross flexing, in which it can take an early game on Fox and flex it into the late-afternoon slot on CBS so more of the country can see it, or vice versa with Fox or CBS getting a late-afternoon game that had been scheduled for an early start in return.

It's all designed to bring maximum exposure to the best possible matchups, according to league sources.

Final details are still being configured, but change is coming. The league first unveiled its flexing system in 2006.
