I don't really disagree with your point, but I also want to push back on the idea that he lacks playmaking ability under pressure. Like a lot of young men, he wants to do the things he is good at and comfortable with - especially in front of a large audience. He loves plays where he can use his quickness to shake guys and get open for a short pass. That's his wheelhouse, and it's on full display in the tweet I posted. There are plenty of others. The one against KSU is pretty neat.
Most of his drops (and where he looks lazy) come from those deep balls that he sucks at catching. And he knows he sucks at them. He's slight, and easy to knock of his route. He's bad at tracking balls. He's got vertical speed, but he doesn't know how to translate that into catches. Look at how he reacted to catching that deep pass in the spring game - he's almost as excited and surprised as we were.
I think it's pretty clear that we didn't intend to use him that way when Neyor was still healthy. It's not playing to his strengths as a receiver. Yeah, he could have put more effort into it, but I sympathize with his frustration (which may have led to an apparent lack of effort). The coaches asked him to do something he's bad at, in front of a national audience. He failed and people now call him lazy.
I still think he's a playmaker and we should be throwing him the ball with the game on the line - but in the right situation. Like you, I would prefer that he put a little more fucking effort into deep routes (instead of acting like a diva), but asking him to do something he's bad at isn't going to have great results. He's clutch when he's used correctly.
