a lot more common in the NFL..... more football players rather than 'combine players'.
When I watch Kupp, (whom everyone here knows I'm very hopeful about), I don't see some flashy, amazing, filled with unique tricks athlete... I just see a very hard working, dedicated, down to fundamentals individual who knows his role and goes for it.
He possesses a trait that I, personally, lack.... he can give 100% concentration to one specific thing.. for as long as it takes. He's focused.
