Carnell Tate stayed and many thought he'd transfer.
Ohio State is kind of like Texas and Georgia in that they lose a lot, but they also return a lot of talent. Georgia got really hammered and loses 18 of 22 starters. Texas lost 13/14 and OSU lost like 16. They return Downs and Styles on defense, losing the other 9 starters. They return Smith, Tate, and 3 OL but they lost the other 6 on offense, including weapons Judkins, Henderson, and Egbuka, and both OTs and the injured OTs before them.
They brought in quality transfers at TE, RB, and 2 OT. They'll be playing with an inexperienced freshman at QB unless they buy one in the spring window. The defense is a complete rebuild with a new coordinator.
I think Ohio State will be a top 20 next year, with potential to go top 10 if the transfers fit, the OC and DC hires are great, and the QB is worthy of the hype. They've basically not been out of the top 25 in over a decade, so I'm not going to bother considering a real downside for those shitheads.
Of course, it's almost impossible to really think through any team's 2025 outlook until the spring portal closes.
