I'm not saying he's perfect, but you've cherry picked a few bad passes (against a secondary with two second round draft picks and a fifth rounder) and based your judgement off those? Laughable. I pick the 2017 deep ball to Siaosi Mariner @ BYU and the 2018 deep ball to Samson Nacua vs Stanford and counter that he may be the best deep ball passer of all time (both under pressure, on the move). /s. Both of those were under pressure on the move.
I agree that he doesn't have great touch on short passes, but you can't argue that his completion % was bolstered because that's all they asked him to do. It's one or the other.
Congrats to your son on making it to the next level, but forgive me if that doesn't make me believe that your assessment of Huntley's QB play is accurate after having seen him in a couple games. I might agree that he is an average passer due to some of inconsistencies, but by no means is he a "poor passer" as you stated.
