Which last shot? You mean the one where JB said he tried to make the best of a bad situation because someone else missed their assignment? Cooney has never tried to be a hero. He's all about team. To think otherwise is foolish.
Look, I want to preface this by saying I dont wish to anger you again, but sometimes I feel something is even more important than I normally do. I'm a Cooney supporter(I'm a supporter of every player, including Chino, Kaleb, Christian White, and the other walk ons as well), but even I find that statement a little too absolute for us to be certain of. Some people may even consider volume rather than
just timing of shots to play a part in reading a player's mind(conscious or otherwise).
It's kind of difficult to say he's
never tried. For what it's worth, maybe his subconscious hasn't been conditioned to allow him to be, and has prevented him from being such(I've personally noticed the differences in my own performance when having certain observers, not entirely dissimilar to the understanding of particle observation determining its behavior in quantum physics). Maybe having Cooney's subconscious being accepting of hero status wouldnt be the worst thing for him or the team. Who knows? Either way, I wouldn't deem it foolish to consider, and don't think it foolish to even consider at at least some point in his career he may have tried to be a hero, even if asked to.
Edit: I re-read the example you used, and can agree that he likely had no intention prior to the inbound of doing what he did, per JB's presser statements. I'm just clarifying whether you meant at no moment in the entirety of his career or not. I agree that that particular play had multiple errors bigger than Cooney's missed shot.
