What happens in 2020?
You recruit a QB in this class & recruit a QB in 2020 too, if Jarren, Perry or Tate are still here then they'll compete.
Clemson had a 2 5-star QB's already on roster, still took Trevor Lawrence & pushed the upperclassmen out, and they took Taisun Phommachanh for 2019 & guess what... They're gonna take another QB in 2020 too.
Bama has 4/5-star QB's on their roster every year, they still take more in every class, same with Ohio St, Oklahoma & just about every other major winning program.
You take a QB in every class & if a QB pops up in the Portal that's good & can help you win, you take him too.
Competition is the name of the game, no program rests on just one player, if a QB leaves because another is coming in, oh fckin well, good luck to'em & the show rolls on.
This ain't the Richt era anymore, QB development is going to be a real thing now, the days of landing one kid & holding on for dear life trying to stash him on the bench for 4 years hoping he finally picks up the offense are over. If you can play, you'll play. Doesn't matter if it's a True Freshman, Redshirt Soph or a Grad Transfer Junior/Senior, they will all compete & may the best man win.
