IMO, CKD is a far, far better choice than Kiffin. Just the record shows that: 2-19 vs ranked teams for Kiffin, 12-2 for DeBoer. And I doubt that Kiffin would have staunched the exit any more than DeBoer, at least not much. Only 9 have left. IMO, only Downs is irreplaceable, Amos might hurt, but the rest including Bond, are not much of a loss, if any. Of course, Sayin might be one, but not for the upcoming season. If it stops with little more attrition, I still think it will not be a rebuild and the team will likely have a decent chance of making the CFP next season.
Not replying to you, but to others regarding this being a portent of recruiting to come: CKD has lost 9 players and kept ~75. But IMO, this is not a good indication one way or another. UGA has lost 20 to the portal this year, causing many UGA fans to lament
But there are surely more losses to come, but at this moment, this roster is still sufficient to produce a good year.
I'm so grateful that Alabama/Byrne did not fall for the Kiffin fix.
