Beckham misjudged that ball

He didn't need to jump, all he had to do was continue to run the route. Ball would have landed at the 50 or 49 of the Packers, he makes a high point of contact at the 47 and starts his jump with the Ball still 4 yards from him. Cant tell me he couldn't have ran an extra 2-3 yards and caught the ball in stride.
Sometimes these receivers tend to make the catch harder than it has to be. in this case I truly believe he did just that.
