I agree with everybody else, but honestly, here are the numbers that you really care about:
40 times
Josh Gordon 4.35
Demaryius Thomas 4.38
Jerick Mckinnon 4.41
Lesean McCoy 4.45
So if we combine those numbers, Gordon and Mccoy come out at 8.80 seconds and Thomas and McKinnon come in at 8.79 seconds so they are clearly the correct choice because they are faster.
