Dabo is a really good guy, but I long have maintained he stuck gold with his OC and DC picks year ago. He lost his OC going into this season and Clemson's offense struggled. It remains to be seen if their defense stays a top 5 unit as they have been all these years with Venables. In short, we get to see how Clemson looks without the two guys that kept them a top program in the nation. Dabo has his work cut for him in 2022 if this year's offensive struggles are any indication.
As for OU, it's a smart choice. While their offense is usually high octane, the defense is what has held them back for a long time. It makes sense to go get one of the top defensive guys in the nation.
