4) and yes I saw that Keenum threw as fast as Russell Wilson, but see number 2
Looks like a weeding out stat if all you get is the number and no video. Anyone below 50 - red flag. Above that pretty much no correlation to success or functional arm strength. Basically any decent QB can load up and make the gun read in the 50's for a few throws. With the video you would be able to see Flacco doing it with ease v. a Schaub/Bortles having to load up to do it.
