Wait, which season? If you mean 2023-2024, he was right: UNC was a 1 seed in the NCAA Tournament. If you mean 2024-2025, he did this
video, where he specifically does not include UNC among the 10 teams that will win the next national championship:
Goodman is asked about teams from a list. Kansas, Connecticut, Alabama, and Houston get an "absolutely", while Duke, Baylor, Purdue, Iowa State, and Auburn get a "yes". Goodman then casts his write-in vote for Creighton. UNC, Gonzaga, Arizona, and Arkansas get a "no".
I guess both can be true. Maybe he sees the Heels as a preseason top 5, but not as a title contender.
