NEW YORK (AP) The new playoff system means big money to the schools in major college football, as much as a half billion dollars per year just in television rights alone. That has Texas coach Mack Brown, among others, wondering if some of that windfall ought to be heading the players way. Soon after the new playoff format was approved by university presidents Tuesday in Washington, Brown tweeted: “In my opinion, with the amount of money the playoff will generate, I hope we can revisit the student-athlete stipend.” Even before the playoff plan had a presidential seal of approval, a group of former and current athletes was pushing for some of the newfound wealth to be spent on player safety and health.
