I believe the new NCAA "5 for 5" rule starts this year. 5 years to complete 5 years of eligibility, no more redshirts but can play for 5 years. Lots of talk about this regarding hockey but will impact football as well. No more limit of 4 games played to keep redshirt.
From a google search:
The NCAA’s "5-for-5" rule is a Division I age-based eligibility model that allows student-athletes to compete for up to five seasons within a five-year period. [1, 2]
The NCAA Division I Cabinet unanimously adopted the rule to streamline roster management and eliminate archaic redshirt requirements. Key structural details of the rule include: [1, 2]
Clock Start Date: An athlete’s five-year eligibility clock begins at their initial full-time college enrollment or at the beginning of the academic year following their 19th birthday, whichever occurs first. [1, 2]
Elimination of Redshirts: Traditional redshirt years and sport-specific eligibility waivers (such as medical hardship waivers) are largely eliminated. Because every athlete is allotted five seasons, developmental and injury-plagued years are naturally absorbed without the need for extensions. [1, 2, 3]
