The Pagliuca stuff isn't great, but to me it comes down to how much Chisholm owns. The NBA requires a controlling owner to own at least 15% of the franchise, is Chisholm just meeting that minimum or more? PE firms are notorious for using significant debt to finance their acquisitions. How much debt is involved here? The fact that Sixth Street, a PE firm, is putting in at least $1b isn't the best sign (I'm guessing they're going to own 20%, since that's the max a PE firm can own in the NBA).
Having said all that, I'm not quite ready to panic because, to me, there's a difference between someone in private equity owning a team on their own versus a private equity firm owning the team (see the fact that there are quite a few PE involved in the current ownership group), but we're going to need to find out more info on the financials before we can really see what the deal is. I'm sure there will be a lot more coming out in the coming weeks, but if you're hoping the deal will fall through, I wouldn't hold your breath.
