Well, now, let's not take tdub's word for it...let's use MATH. Let's use the motherfvcking Pythagorean Theorem.
Soooo...
Ball was thrown from the 45 yardline. It crossed midfield and was caught at around the 22 yard line. If it had hit the ground, it would have landed at the 20, so for MATH purposes, and to make the math simple, let's say the ball travelled downfield 35 yards.
And then, the ball was thrown from the far hashmark to the opposite sidelines. A football field is 160 feet wide. High school hashmarks are 53 feet, 4 inches apart. Which means that the (collective) distance outside the hashmarks is 106 feet, 8 inches, which is 54 feet, 4 inches from each sideline to each hashmark. Which means that the distance from the far hashmark to the opposite sideline is 105 feet, 8 inches. Or, in yards, 35 yards.
And I think you see where I'm going here.
A 45-45-90 right triangle with each of the two legs being equal (each being about 35 yards) would allow you to calculate the hypotenuse (actual distance travelled by the football) by multiplying 35 times the square root of 2.
Which would come out to 49.5 yards.
So, yeah, even a blind guy could figure out that the ball was thrown about 50 yards in the air.
