In early 2023, as Diamond Sports Group entered bankruptcy and its regional sports business appeared to be crumbling, a veritable flock of vultures began to fantasize about picking up the beleaguered company’s cache of local sports rights on the cheap. These opportunists ran the gamut from almighty streamers to local broadcast channels. But two years later, most of them are still waiting for their moment to pounce. During the annual National Association of Broadcasters convention in Las Vegas this week, the local broadcast channels preached patience. They’re still interested in picking sports rights off the carcass of the R.S.N. era, but “it’s still the second inning,” Scripps Sports president Brian Lawlor said during an NAB panel session.
