The NFL is testing out the ability to use Microsoft tablets and video on the sidelines, seeing what it could mean for the future of the game. Cardinals coach Bruce Arians noted they had them in the first preseason game against the Raiders.
"I watched one play the referee called holding and it wasn't holding and I showed it to him," said Arians, referring to a hold called on tight end Troy Niklas that Arians had previously complained about. The penalty negated a touchdown.
"I said (to the official) this would be your worst nightmare if I had this on the sideline," Arians added.
That drew a chuckle in the press conference, but Arians was serious when he said he hoped video was never part of in-game use on the sideline.
"Helps bad coaches," Arians said. "You spend six hours on a blitz (for your defense) on Tuesday, he can watch it … offensively you don't run the same plays very often but defensively, you spend a lot of hours and time on a blitz that a guy can watch it on tape and show his guys and fix it in the first quarter.
"That's not what it's all about."
