I don’t think it works that way, or at least it’s not that simple: “I’ve seen a high school receiver make that play, therefore, NFL receivers should make that play.
Does that high school receiver have a QB w/an NFL caliber arm throwing with the type of velocity a NFL can? Were the plays you seen high school players make the exact same plays you’ve seen our WRs drop, at the same depth, against the same coverages, et cetera. There’s endless variables. I would agree, that your average NFL reciever is much more capable than your average high school reciever, but it doesn’t mean the professional will make the play 10 out of 10 times.
Ive also seen high school athletes do things on the field I haven’t seen in the pros.
The point is when you make an inaccurate throw, it raises the level of difficulty. I think of specific throws where a Cowboys reciever is running full speed across the field and Dak has placed the ball down and behind the reciever.
