Ehhh it seems pretty specious to me. The main reason they give for selling it is the glut of banked points? Thats an issue sure, but an insurmountable one to where you'd want to sell the division I dont think.
Unless you're Bob2 and want to have cash to buy a sports betting outfit for the synergies that provides with ESPN, but really I dont think Disney would need to drum up that much cash to do that deal, sports betting is still in its infancy for being legal in more and more states, surely an all stock deal would get that done without the need for any actual cash to change hands.
