It got revisited because Alex Cora posted a bunch of photos of him going out with the boys on IG. Then people online started talking about it and found the stuff in Drellich's book. Articles were written a few days later. Media need an easy story and it was one.
We've seen them really throw a lot of people under the bus in the past, but it seems Breslow didn't really do that this time. He's even downplayed some of the speculation about Fatse getting fired because of KC's performance. Breslow keeps a lot of things close to the chest and doesn't seem to leak much. If anything is getting leaked, my guess it's from Sam and friends rather than the CBO side of things. The only story we heard was that they were upset with how well DHam played and that Breslow had wanted to clean house when he first got there or whatever. Uh, ok? In terms of mudslinging, that doesn't hold a candle to what they have done in the past.
