Arians: In-game video 'helps bad coaches'

Bruce Arians is one of the league's best and most effective coaches.

He knows it and he wants to keep it that way.

The NFL has been experimenting with the use of in-game video on the sidelines during the preseason. The Arizona Cardinals used it against the Oakland Raiders and while Arians admitted the technology works, he says it's going to make things easier for lesser coaches.

"It helps bad coaches," Arians told Kent Somers of the Arizona Republic of the in-game video use.

Arians' biggest issue with the video is the advantage it gives to offensive coaches over defensive. While offenses rarely repeat a play call with much regularity in one game, defenses tend to use the same schematics over and over.

"Defensively, you spend a lot of hours and time on a blitz and a guy can sit there, watch it on tape, show it to his guys and fix it in the first quarter," said Arians. "That's not what it's all about."

Arians also pointed how annoying the video could be for officials if coaches can get a close-up look at replays on a regular basis.

"I showed (the video) to (the official) and said, 'This would be your worst nightmare if I had this on the sideline,'" said Arians.
