Eventually we’ll get an opportunity to look at two similar throws between Haener and Carr to see the difference in the time between the QB’s hands breaking from the ball and the ball reaching the target. The closest one I could find from yesterday was around a 25 yard throw for both, with Haener getting there a quarter second late. That amount seems trivial, but people fawn over players that might have a 40 time that is less than a tenth of a second faster than another player at the same position.
Also, I remember a great interview with Roman Harper where he discussed that one false step playing defense in the NFL can be the difference between 4th down and a touchdown. The margin for error is so small. The same goes if the ball hangs in the air to allow extra step(s) for the defense to make a play.
