Good to see Delaney retire. I was not a fan. He did a fine job establishing the cash cow that is BTN but made some real blunders as well like hosting the B1G Tourney in New York, bringing in Rutgers and Maryland, signing with the Pinstripe Bowl, etc.. He is an east coast guy who grew up in NJ and went to school at UNC so his east coast bias was pretty strong.
Warren seems to have a good background and certainly understands the business side with all his years in NFL ops. Alvarez would have been another good choice but choosing an existing AD within the conference could bring a negative vibe for some.
