And this is plain baseball nerd talk..
.. his arm rates out at a true 80 (though his arm action can get a little long – I’ve caught pop times in the 1.7 to 1.8 range) -- more, he couples 80-strength with good accuracy.
...he also can get in the habit of rotating his body when he collapses his left side mid-pitch
... good bat speed and excellent torque through his core. His swing got long and a little loopy towards the end of the summer
I want all my catchers to have excellent body torque with 80 strength at 1.7-1.8 range. But watch that collapsed body mid-pitch!!
That stuff's really not that hard to understand with minimal effort.
