Basically, dilution is much more likely to mean an infusion of cash into the business. It does get a bit tricky, depending on the Sox structure and agreements in place with limited partners (which I'm not going to pretend to understand or even speculate on), but assuming the double value was enough to dilute their percentage without diluting their value and they were on board with the perspective long-term growth from Ishbia's capital infusion, they could have agreed to allow Ishbia to create additional shares and increase cash flow and valuation for a stadium agreement and other capital needs.
In this case, given that there is no additional share creation here, I find it much more likely this is merely a pathway to an outright sale. Unless there is some clause in the partnership agreements - which I highly doubt - Jerry can't force the limited partners to sell, meaning in my opinion, 1.8 was the price they agreed to sell out at; at least the majority of them.
Edit: I like to think they're reading Soxtalk and saw our conversation on dilution so they circled around and updated their article.
