The NCAA is set to dramatically change how collegiate eligibility is determined.Rather than limiting players to four years of eligibility, the NCAA is adopting a "5-in-5" rule at the Division I level. This also makes eligibility age-based, as the clock starts when an athlete enrolls in school or on their 19th birthday, whichever comes first. Such a change basically does away with redshirts as well. It has also given several key Michigan State athletes another season of eligibility.Coen CarrMichigan State's Coen Carr looks on during a game against Michigan at the Breslin Center on Friday, Jan. 30, 2026. | Starr Portice, Michigan State Spartans on SIThis rule change would give Coen Carr the option to play a fifth season at MSU if he so chooses. Carr is entering his true senior season in 2026-27. His all-world athleticism has allowed him to go viral plenty of times with his dunk-contest-worthy slams, but the lack of a reliable jump shot has kept Carr from leaping to the pros. Carr shot just 27.6% from behind the arc last season.Getting this extra year should spare Carr from some pressure this year. This doesn't necessarily have to be the "all-in" year for him individually, since he'll be able to return to college for '27-28 if he needs to. Michigan State's Coen Carr defends against Louisville during the second round of the NCAA Tournament at the KeyBank Center on Saturday, March 21, 2026. | Starr Portice, Michigan State Spartans on SI"Yeah, you're not trying to think about that too much," Carr said when I asked him about it on Tuesday at the Moneyball Pro-Am. "I kind of just try to be in the moment, not trying to think about the future too much... Of course, though, it's going to be in the back of my head, because I obviously know what it is and everything."Carr averaged 12.0 points and 5.4 rebounds per game last year. That's without a reliable jump shot. If his three-point percentage gets into the mid-30s on similar volume, Carr probably won't need that fifth year. Still, the option will be there come April and May 2027.Anton BonkeMichigan State and Team Motorcars’ Anton Bonke shoots a free throw against Team Faygo during the Moneyball Pro-Am on Tuesday, June 23, 2026, at Holt High School. | Nick King/Lansing State Journal / USA TODAY NETWORK via Imagn ImagesAnton Bonke will also get the option to play another college season. He'll also be a true senior during his first season with Michigan State after transferring from Charlotte. Bonke spent his freshman year in junior college at Eastern Arizona, went to Providence as a sophomore, and then transferred to Charlotte as a junior.Bonke and Carr are actually the only scholarship players entering their senior years. There should be some NBA Draft and maybe transfer portal decisions to be made following the 2026-27 campaign, but Tom Izzo could, theoretically, bring back the entire roster for '27-28.Jordan HallMichigan State's Jordan Hall celebrates after a stop against Michigan during the second quarter on Saturday, Oct. 25, 2025, at Spartan Stadium in East Lansing. | Nick King/Lansing State Journal / USA TODAY NETWORK via Imagn ImagesSwitching over to football, star linebacker Jordan Hall will also get the option for a fifth season. Redshirting was much more common in football than basketball, so the impact of '5-in-5' is a little less prominent there. Alas, Hall played right away at Michigan State during his true freshman season.Hall could very well be NFL-bound following this year. He led MSU with 88 total tackles, with three forced fumbles as well. Sort of like Carr, this just opens up the interesting possibility that the coming season may not necessarily be the last one we see Hall in a Spartan uniform.
