Tangent

I've been surprised and impressed how the mechanics of throwing the football have changed since I first learned to throw a football.

It's always been about the torque in the lower half, but the changes in how to create the torque (and the subtle changes to footwork and positioning to create it) along with how to more quietly unleash the torque (off hand placement not pulling through but staying tight near the helmet, along with not getting flat as a requirement which elongates everything. Getting flat/perpendicular was beat into my head and others, when I was a kid. We spent 90% of our time on creating a repeatable whip motion. I crapped out early on and found other positions).

I know you know this, but watching Purdy's mechanics is amazing. Hearing Tom Brady and Drew Brees talk about the evolution in how they learned to throw (those dudes are my age and learned the same way I did as kids, but spent their entire NFL career relearning and doing it better).

NFL throwing mechanics have come a long long long way the past 15-20 years. Every young kid learning to throw should do a deep dive into Purdy's pre draft work and post draft evolution. It's pretty awesome to watch, and intuitively, makes a shit load of sense.
