If Jake Diebler doesn't beat #2 Purdue in his coaching debut, is he Ohio State's head coach? Ohio State took the cheapest and easiest way out when they promoted him to head coach. He's got a roster, that let's be honest he built, because he's been a major recruiter for them for years, he's tried the portal route last year and that didn't work out. If they wanted to change things, they shouldn't have promoted from within after Holtmann . They need an outside higher if they ever want to be more than a bubble team.
