If Taulia is our starter next year do you really think Tyson will leave with his family ties?
Assuming both Tyson and Taulia maintain their redshirts this year, and Lia wins the job next year: yes, I do think Tyson transfers. Mac, too.
Assuming Tyson redshirts, and Taulia burns the 'shirt in 2019, it puts them a year apart in eligibility. Tyson might, maybe, stick around, figuring Taulia lasts only through the 2021 season. At which point, Tyson would be a RS Junior for the 2022 season.
I wouldn't count on it, though. Saturday's statement on the #3 QB, as they stand today, was unmistakeable. And today's transfer world isn't what most of us grew up with.
