You can see why.
One thing that doesn't show clearly unless you look for it is how close to the ground he'd sometimes get when making a cut. His experience as a gymnast and hurdler in track were evident on the football field. I don't think I've ever seen another back e run with better balance.
His shoulder-rolling running style was the beginning of a fake in itself. Moves? He seen med to invent new ones every time you wqtched him play.
So many of his best runs were kick returns because his Rams teams were scored on a lot. He'd get several opportunities per game to make a return.
After his career was over an interviewer, after heaping praises on Arneet, asked him if there was anything he wished he could have done as a player. He paused and looked down for moment then looked back up and said, "To play for a winner... to play for a winner."
