If you watch CFF and even to an extent the NFL in 2022 you will see that the QB position has changed dramatically in the last 10-15-20 years. The idea of a "Drop back passer" is extinct. The game has evolved way beyond the Dan Marino, or even Manning type QB's. You have to be an ATHLETE with quick good feet to play QB these days. And that doesn't mean you you have to be Vick. It just means you have to be athletic and very mobile and have the ability to improvise and throw with different arm motions and angles on the move (This was a big NO back in the day). Look at the NFL. Look at CFB.
TVD is not that guy. He is not athletic. He is very heavy and stationary. His feet are heavy and slow and he's not a quick decision maker. His release is slow too, despite his arm. He does not IMPROVICE. TVD would benefit from losing 20+ lbs and doing agility work.
In 2022, most quality HS QB's are trained (Privately and with their HS) to be quick, mobile, and have quick shift mechanics. IMO Garcia is the QB who has the skillset to take BIG steps. The TVD "Hype" was very premature. TVD would not be good in a true up tempo dynamic offence because he lacks the ability to be a mobile threat both in plays called and as an improvised option.
Also, this doesn't mean Gattis is good. He still is horrific and bad.
PS- I grew up believing in the "Pro style QB" era, and had to grow to accept the evolution of the QB position. Bottom line is that you need to be dynamic at QB and have multiple skillsets. It doesn't matter your race, build, etc.
