Good analysis. To me,, and I've been saying this every week, Josh Allen tries too hard to hit these guys in stride with passes that are too flat. He tries to be too perfect. What are the odds of hitting a guy 45-50 yards downfield on a flat rope with a vapor trail?!? 5% -10% maybe? .and even if the timing is perfect and NFL DB will be able to get a hand on it to deflect it because there's no arc. The only time it worked all season was that deep throw to Brown at Miami. In that case Brown was like 10-12 yards past the DB already so a flat pass was fine. Josh's best pass of the season was that high arcing throw into a stiff wind against Denver, deep into the end zone. Gave John Brown a chance to adjust, track it, and run under it... and the DB had no chance of defensing it. It was "dropped in the bucket" as they say.
Josh needs to work on his trajectory and arc. That way he doesn't have to be perfect. Let his guys run under it. He should roll tape of Russell Wilson's deep completions. He does it right.
