FSU's QB has been at the school for 5 years. You don't get much more home-grown than that.You understand the difference between a coincidence and a cause and effect relationship, right? It's like saying the team that won the world series had a shortstop who hit .230, so our shortstop should be hitting .230.
Clemson, who hasn't believe in/used the transfer portal, has dominated the ACC. That's why the winner hasn't had a transfer: The one team worth a damn hasn't taken transfers. In the years when they didn't have a 1st round pick under center it's cost them those seasons, and their fans are pissed. Sure, they were still good enough to win the ACC.
When FSU wins the conference with a transfer QB, maybe we can squash this debate. There's a good chance next year's winner also has a transfer QB.
The point is that top QBs haven't transferred to ACC schools. There is nothing to indicate that will change.
