What could the NHL learn from MLB's new ABS challenge system?

Here’s a sentence you’ve never seen me write before: Replay review is good.And a few more: Replay review works. It’s doing what it’s supposed to do. I’m glad it’s there, because it’s making the game better.Just not in the NHL.Tomorrow will mark the one-month anniversary of Major League Baseball’s introduction of the automated ball-strike system, also known as ABS and/or our new robo-ump overlords. For the first time, balls and strikes can now be challenged, subjecting the fundamental building block of the game to review.And it’s working. It’s working so well, in fact, that some fans and media are asking for more.Advertisement
