I'm sure there's a hell of a lot more to this story. I could easily see a scenario where those reporters have been pestering the front office about Osuna for quite some time, and Taubman being a little drunk after advancing, felt vindicated in taking the chance on acquiring Osuna and wanted everyone to know it, without considering how it might be interpreted. It's also possible that he's simply a prick.
Either way, it's not a good look. He either screwed up without meaning any offense, or it was directed specifically at the female reporters on purpose. Regardless, he screwed up.
