I saw an article:  https://brobible.com/sports/article/philip-rivers-play-style-exposing-modern-qbs/ that talks about how Phillip Rivers (and what Tom Brady talks about a lot) in terms of QBs reading the defense instead of just relying on their raw talent.

This is what I believe Arch is learning to do under Sark, and this takes a lot of experience and time.  Arch also has the physical gifts and abilities as well which is why I believe many people predict him to be great and some even projected #1 pick.  He has the ability to blend both the old school style (from his uncle's day) and the new style of play.

Hoping it comes to fruition fully next year and results in a natty.

Totally agree with you OP! Analysts like Nate Tice love Arch for all the reasons you said. It’s awesome how Arch can sometimes gets to his 3rd or 4th progression, doesnt just bolt at first sign of trouble. Another year of learning, improving layered throws and dissecting defenses at the line of scrimmage is going to be huge for a jump start in the NFL. My dream scenario is McVay gets Arch in 27 😅🤘
