But there is also a science to power generation of the old pigskin. That bothers coaches because of the possibility of getting the ball knocked down.
Goff goes on, "It's also interesting that the ball relies a little more on the fingers for launch speed, compared to a more overhand throwing motion that gets more of the palm involved. Goff finds "Sidearm deliveries cause a little more precession in the spin axis because that axis is usually a little more away from the launch velocity compared to an overhand throw which leads to a little more air resistance for a sidearm throw compared to an overhand throw.
Lower release points also require slightly greater launch angles for long throws. A greater launch angle means a longer time of flight, which might give corners a little more time to get to the ball. Goff said, "Just as a simple example, say that a quarterback wants to throw a bomb, nearly 60 yards.
The quarterback releases the ball at 50 mph with a release angle of 45 degrees, and the ball is caught at the same height at which it was thrown. The ball goes nearly 56 yards down the field in about 3. A well-thrown spiral doesn't have too much air resistance, so those numbers don't change much when including the air.
If you drop the arm a foot like in a sidearm throw such as Tim Tebow's, the range is just a tad over 49 yards and the time of flight is about 3. The conclusion of something like a 12 percent reduction in bomb distance is the new result, as long as one assumes the release speed has dropped 5 percent and the release angle has increased five degrees.
Goff concluded, "The time of flight is just under a tenth of a second longer, which might be enough for a corner to close a little gap that he couldn't otherwise close. Some turned that arm-strength into championship results while others experienced sporadic moments in the spot-light.
Past power-passers such as John Elway, Brett Favre, Jeff George, Drew Bledsoe, Randall Cunningham, Vinny Testaverde, Jim Kelly, Sonny Jurgensen and Daryle Lamonica all dazzled fans through the years with highlight rainbow trajectories deep down field for touchdowns and fastball strikes into seemingly invisible seams through defensive secondaries. Others, like Kyle Boller and Jamarcus Russell, never could harness their arm-power to make it work for them.
In an article posted on Livestrong. Parrish noted that Packer gunner Brett Favre was estimated at 63 mph. Now retired passing star and Hall-of-Famer-to-be Peyton Manning pre-neck injury could hit 59 on shorter throws. According to some, including former Bronco wideout Rod Smith, John Elway brought the greatest velocity to the field. It is said Elway ripped it consistently in the plus MPH. Here is a look at the results of NFL Combine velocity reads from to In some cases the perceived is reaffirmed, but a few surprising speed readings are popped by passers who just may have been mislabeled by more than a few football writers and profiling bloggers failing to pay attention.
The list consists of quarterbacks currently on rosters or actively seeking pro employment, their college, current team if on a roster and their Ball Velocity. Have fun with the comparisons. Velocity is measured by a radar gun in miles per hour. Redskins backup Colt McCoy also falls into the misdiagnosis of a soft-tosser. McCoy hit 56 in a variation test, using a chip in a football rather than the usual radar gun method. Where Dalton, McCoy and others like them may come into question is their ability to muscle-up a pass deep downfield.
The guy has a cannon attached to his shoulder. After just a few practices, the No. Due to the aforementioned broken fingers, when given a choice between catching an Elway pass with their hands or their chest, his college receivers opted to use their chest.
Not exactly the type of choice most people would want to have, though. So who is the hardest thrower in the league today? One way of measuring how hard a quarterback throws is by clocking their throwing velocity, as measured — in miles per hour — by a radar gun. Larsen: We're gonna orient the best we can our middle finger and our thumb in a straight line on the ball, and then we're just gonna wrap our fingers down and let them rest in control.
Narrator: After that, the quarterback's goal is to build up force behind the ball. So, first, they'll load the ball back, with their elbow above their armpit. This helps to ensure that the quarterback is what's called being "on top of the ball. Larsen: The second you're low, now you're, yet again, you're pushing the ball. So when you try to drive that ball deep down the field, you're underneath it, and you're lacking arm strength. Narrator: After that, the quarterback uses their other arm to twist their upper body while stepping forward into the throw as they prepare to release the ball.
But a quarterback could complete all of these steps and never end up with a spiraling football. Getting that spiral comes down to the very last thing the quarterback does in the split second before they release the ball, and it comes back to the grip. Because, in order to generate a good spiral, the last finger that should touch the ball as the hand releases it is the quarterback's index finger.
Larsen: The spiral's created by that final flick, that last finger. You really want that last finger to come off of it and then finish down, and that's that spin that you're trying to get to create the spiral. Narrator: But here's the problem. Even the slightest of errors in how the quarterback lets go of the ball can affect the throw. Larsen: If you're finishing with the ball on your wrist, you're finishing like that, now your index finger's not the last finger.
Now you've got multiple ones, and that's when you start to get balls that get wobbly. Chad Orzel: Really, precision in the release and in the flight of the ball is absolutely critical to success if you're gonna be a passing quarterback.
My name is Chad Orzel, and I am a professor at Union College in the department of physics and astronomy. Narrator: When it comes to how well a football flies through the air, there are two key elements: spin rate and velocity. Let's start with spin. On average, a good spiral has a spin rate of roughly rotations per minute.
That's as fast as an electric screwdriver. Orzel: If you get the ball spinning rapidly, the ball will tend to stay with its axis of spin, pointing in the same direction all the time.
