Go outside. Take a football. And try to chuck it as hard as you can - not just hard - but as hard as you possibly can. See how accurate you are.
Do the same thing with a golf club and golf ball. See how straight you hit it.
a long retired David Carr (taking turns with Mahomes) did it with ease - hit the receiver in the hands every time and was only 2 to 4 mph slower than Mahomes on most of the throws. Again, I don't want to make it seem like I don't like the kid a bit because I do... Just not a rd1 guy. Mitch T has the accuracy that Mahomes lacks, but then Mitch is a one year player so... we'll see. I don't like any of the Qb's for rd 1, but especially at #10
