This is great data. I think one of the keys to success that can't be quantified (especially since the success ranges all over the place as it pertains to athleticism) is their ability to A see the game and B be on the same page with their QB in how he sees the game. There are some athletic marvels thrown in but the majority of the guys on these list are players you'd consider savvy.
Great route runners that are smart and know how to set up their opposition. They are smart enough to adjust to what coverages are being thrown at them (since teams play Zone more than man these days) and find open spots in areas.
In a nutshell while their athleticism scores all range differently it's not arguable that they all play the game FAST.
