Ive watched a good amount of Penix film and theres a lot of issues with his tape
the main one - and its well documented on many scouting tape discussions - is that if you muddy the pocket his effectiveness takes a nosedive. he has issues throwing from various platforms and he is not a good outside the pocket
if you picking penix, you need a very good to elite oline play on obvious passing situations that can keep him clean, and dont expect many outside-the-structure plays like, say, Caleb does routinely
what worries me particularly - and this is my take on it - is that I saw similar issue with daniel jones pre-draft. great from inside the pocket, but navigating the pocket and pressure in his face really changes his play. not saying penix is daniel jones or anything, but just similar issues in their game
this is an article where even tho I disagree with the conclusion - I think penix is a first rounder, it kinda touches on the flaws:
Penix has helped carry Washington to the doorstep of a national title. How high can his ceiling be at the next level?
