NEW YORK (AP) - NFL teams used to take Polaroid pictures of plays from atop the stadium during games then send them down to the field on a rope.

Technology improved so that an automated camera could deliver the images to a printer on the sideline, creating that familiar sight of a quarterback staring at a sheet of paper to figure out what went wrong on an interception.

That was still the case last season, when fans in the stands could watch highlights on their smartphones, but players and coaches were flipping through three-ring binders of black-and-white photos.

The NFL sideline is finally catching up.

Sort of.

Tablets were allowed for the first time Sunday night with the Hall of Fame game, although a few kinks had to be worked out early on.

“I was told mine was going to work, and mine didn’t work,” Bills coach Doug Marrone said after his team lost 17-13 to the New York Giants. “They said they would get it right and there was miscommunication.”

Marrone said that the tablet did work in the second half and he “liked it a lot.”

The tablets won’t exactly be running the most cutting-edge apps. The devices will replicate the old system of transmitting still photos to the field - but faster, clearer and in color.

No surfing the Web. No selfies or tweets. And more important from a football standpoint: no watching replays of the last snap.

“The purity of the game has always been not having video,” Tennessee Titans coach Ken Whisenhunt said. “So when you’re looking at pictures you have to sometimes guess, or a lot of times the pictures aren’t what really exactly happened. That part of it is still coaching, and I kind of like that.”

Indianapolis Colts tight end Dwayne Allen, though, suggested that allowing video would improve the sport by making games even more competitive. And just as instant replay, once revolutionary, is now widely accepted and has been expanded over the years, the same could take place with the tablets. Adding video is possible in the future, NFL spokesman Brian McCarthy said.

That would need to go through the league’s competition committee, just as the introduction of tablets did. The NFL signed a sponsorship deal with Microsoft last year, which includes the standard promotions of sticking the league’s logo on products and a more sophisticated collaboration of making NFL content available on Xbox.

But the company also became a sort of bonus IT department, engineering its Surface tablets to withstand the rigors of the NFL sideline. Searing heat in Arizona. Pouring rain in Seattle. Frigid cold in Green Bay. The screens had to be viewable in the glare of the sun.

And the devices couldn’t be vulnerable to hacking - a real concern in a league famous for paranoid coaches, where the term “Spygate” was spawned.
