Nobody here knows Jalen Carter. You have no idea what he’s like, how he feels, or really anything about him.
What you do know is how you would feel and your expectations of how someone should feel in this situation. It’s not the same and it’s not relevant in this case.
The words “maybe”, “possibly”, “could have”, “would hope” are all littered through this discussion. What isn’t speculative is that he was out of shape and couldn’t finish basic combine drills at his all important workout. That’s all that we know for sure.
