I don't think that's obviously true, at this point. Losing Colvin and Heide, I think, is a pretty big blow. Cox and Harris are solid, but they're both on the small side, and won't be much help guarding/rebounding with any guards/wings with length. And as I've said, while Cluff is a very good basketball player... he changes the dynamic a fair bit... kinda back to how they played with Edey/TKR...but Cluff is no Zach Edey... no rim protection, no domination in the post = less double teaming, less open looks for Loyer/Smith/other perimeter guys. Daniel Jacobson, AND guys like Colvin and Heide, were the guys that were going to get Purdue back to being a legitimate top 10 team, like they were under Edey. 2 out of those 3 are gone. And Jacobson got recruited over. He'll still play, but he'll be a 15-20 mpg guy now, tops.
The context of all of this is if they want to be top 10, Final Four competitive. They'll continue to be top 4-5 in the B10, I'm sure.
