    Linky for calculating a trajectory: http://en.wikipedia.org/wiki/Trajectory

    Good luck with this one! I'm not gonna attempt it.

    Still, it was one of the best throws I've ever seen.

    Bingo. If you and many others can figure that out why can't these highly paid 6 and 7 figure analyst do the same?

    Fucking joke.

    It was thrown by Flacco. It made Denver fans yell "F*ck!", and it made me yell "F*ck YEAH!!"
    I like that better than the Mile High Miracle. I will add this to name thread and give you credit.

    Tell me how long the ball was in the air, as accurate as possible, and I'll tell give you my best guess as to how far it traveled.

    God, so hard to tell with angles, foreshortening, etc... but I'm guessing at least 40ft.

    I get 96 frames on the player with a frame rate of 29.970628.

    Comes out to about 3.2 seconds.

    That is why is was completed. Moore had no idea that the ball could be thrown that far, and it surprised him.
    This was exactly my assessment of it. Moore was the goat, but I think he wouldn't have been the only one, in a similar situation, to make the same mistake. That ball just never seemed to lose trajectory. Sorta like a ball that keeps carrying over a centerfielders head.

    It was a perfect throw. All the kvetching about Moore misplaying the ball ignores that Jones misplayed it as well. I mentioned it on another thread.

    Jones turns his body so he's facing the defender, which would have given Moore a chance to get his arm in there if he'd played Jones instead of trying to play the ball. I don't blame Jones- I don't know that he's capable of making the over-the-shoulder catch like we saw Boldin do against the Irsays- but it is what it is. The way Flacco threw that ball, if Jones plays it right the only chance either DB has of stopping the catch is to interfere with Jones. That ball nearly dropped straight down into his arms. That's awful tough to defend.

    If there's another QB in the league capable of making that throw, I haven't seen him do it.

    Re: The Arc on Joe's ball.

    Ran a couple of calculations. Using 3.2 seconds as the hang time (which is what I calculated with a stop watch, but someone else just verified) and the 59 yards traveled estimate, I calculated an initial velocity of the throw at 23.02 meters/second (which is roughly 52 mph). Using that, I got a 42.92 degree launch angle. Also, the peak height came out to be 12.5 meters (13.7 yards).

    If anyone has any theories as to how to use these numbers to get a distance of a curve, feel free. I have no idea.

    More impressive is that the bail didn't hang... it still had a ton of velocity. Is Sports Science on this?

    And, I think Moore was in position for a standard deep throw. It was the arc that put it over his head. Moore misplayed the arc, not the distance.
    Haha it only takes pre-Algebra to calculate. Just draw a triangle from where Flacco was when he threw the ball, to where Jacoby was when he caught the ball, and then draw a straight line back to where Flacco was when he threw it, and then finish connecting the dot. Then just do the Pythagorean theorem.

    But it will be hard because it's hard to determine how many yards the ball sailed to the right.

    EDIT: Oh, you mean including height and stuff. Oops.

    This is the greatest and funniest thread I have ever seen. Love it.

    I estimated the distance to the right as the distance from the hash to the sideline (the ball was thrown from and caught within a yard of two of each). Knowing that the has marks are 18.5 feet apart and the width of the field is just over 53 yards (2x+18.5=160), I estimated the short leg of the right triangle to be 24 yards. That's what gave me the 59 yards total.
    Long days and pleasant nights.
