How would anyone know if he lost a step? And 32 isn't old for a pro athlete. I'm sure he has no need to run a 40, but he might be able to meet his old time. Some athletes work hard to improve their bodies after getting drafted. Kupp has gotten stronger and faster. He always ran great routes and had plus hands, but now he has it all.
He works at it. AD works like a maniac do that he doesn't lose a step. Pretty sure our new MLB does the same. You don't make 170 tackles by being slow. Can't wait for the draft.
