You're speaking in absolutes as if there's only one way of thinking that's right.
The truth is somewhere in the middle (as it almost always in these CIS arguments).
You can take a variety of approaches when it comes to QB but the fact is, most high school QBs are busts.
For every Drew Allar (class of 2022) there is also Cade Klubnik, Ty Simpson, Walker Howard, Devin Brown, Gunner Stockton, Sam Horn, Nick Evers, Brady Allen, AJ Duffy, Tayven Jackson, Katin Houser, etc. Most of those are busts or jury is still out but likelihood they bust.
For every JJ McCarthy (class of 2021) there is also Quinn Ewers (transfer), Caleb Williams (transfer), Sam Huard (bust), Brock Vandagriff (transfer), Kyle McCord (transfer), Ty Thompson (transfer), Jake Garcia (bust), Jaxson Dart (transfer), Tyler Buchner (bust), Kaidon Salter (transfer), Carlos Del Rio-Wilson (bust), etc. Milroe and Stone are solid QBs though from that class.
The list goes on and on and on. The odds are most QBs in each class end up busting.
Should we take a good QB prospect every year? Yes, absolutely. I don't think anyone is saying we shouldn't.
But unless you're a QB whisperer, which Mario isn't, then is there also a different approach to take by investing in proven commodities and getting a better bang for your buck. You still need to play both sides of the coin but it's a reasonable strategy.
