When the NCAA introduced its new "five-for-five" rule this summer on player eligibility, it changed several aspects of player management in college football. The rule eliminated redshirts and eliminated almost all waivers for extra seasons of eligibility. Going forward, each player gets five years to play five seasons. Once your five years are up, your college career has concluded, even if you missed multiple years due to injury.

The rule change certainly affected the Oklahoma Sooners. Head coach Brent Venables and his coaching staff now have a clearer picture of how to manage the roster going forward, as do general manager Jim Nagy and his front office staff. Without redshirts, and with stricter guidelines, teams know exactly how many years a given player has left to play college football. Of course, players regularly leave early for the NFL draft, forgoing their right to compete at the college level before their eligibility is up, but coaches and the front office typically know that's at least a possibility coming into the season.

However, not all Sooners fans may know how much longer their favorite players can play at OU, especially as the new rules have only recently begun to be implemented nationwide. Of course, in college football's NIL-transfer portal era, no one can guarantee any player will stay at any school for more than one season. However, Oklahoma has shown a pattern of doing what it takes to retain what it believes are its best players, and they don't typically hunt in the transfer portal the way other teams have in recent years.

With more certainties added into the picture when it comes to player eligibility, but all of the uncertainties still swirling around when it comes to what players will actually stay at which schools, let's take a look at each of the 113 players on Oklahoma's roster to track how many seasons of eligibility each player has left.
