Ok, so I am doing my Monday morning routine, which is re-watching the game and being daddy to my little girl.
I decided to actually stop the game on the kick return, and check out the clock. At EXACTLY 14:54 (just the frame before it turns to :53) Antonio Brown was at the 47 yard line, a 40 yard dash would put him at the 13 yard line... at which time the clock says, 14:50 That means he ran 40 yards in aprox 3 and a half seconds. I verified it looking at the FPS, (36 FPS, 115 frames) it came out as 3.2 seconds!! :jawdrop:.
BUT, Brown was looking BACKWARDS for the last 10 yards of the run, slowing down. In frame by frame, you see that he was running 10 yards in what seems an average of 7.7/10ths of a second (36 frames per second, 28 frames on the TV, split into 10 yards, there was 27, 28, and 29 frames per 10 yards, avg. a little under 28, verified by taking the avg FPS times 4, getting 117 FPS, just two frames off. Also the 29 was when he was running around the kicker, which is prob. what through off the numbers). So, for the last 10 yards, when he was looking back, timed out at 30 FPS, which is 8.3/tenths of a second. Thus, he gave up a .05 seconds. That means he was actually running the 40 yards, before looking back, at 3.15 seconds
Just how fast is that? Let's compare it to Usain Bolt, the "Fastest Man in the World." In his 100 M dash, he ran the his fastest 40 meters towards the end, with 10 meter splits, .82, .82, .82, .83 . Now, Add those together, and you get 3.29 seconds for 40 meters, vs. 3.15 seconds for 40 yards. So let's equate them...
40 meters = 43.75 yards.
3.15 seconds for 40 yards equals .07875 per yard. 40 meters = 43.745 yards. 43.745 x .07875 = 3.444
That means, in the fastest 40 yards of Usain Bolt, Brown was only 15/100ths of a second slower, or 1.5/10ths of a second slower than the "Fastest Man in the World".
Oh yeah, Brown was also wearing a helmet, shoulder pads and carrying a ball. Does that equate to 15/100ths of a second? I sure think it might.
EDIT: Please read again, THE FASTEST OF USAIN BOLTS 40 METERS. That means neither his starting 30 meters, nor his last 10. It is actually, meters 50-90, or his fastest forty meters of the entire sprint.
