An average NFL game has 20 cameras, 7 on-field officials, officials in the booth, instant replay from multiple angles, and an entire pace of game that has been designed around instant replay and high-tech reviews of action in real-time. But as Monday night showed, they can still get it very, very wrong have some really really close calls, go Hawks. Even with the best replay systems available. Should MLB continue investigating and slowly adopting instant replay for many aspects of regular and postseason games? Of course. We've all seen places where we see it on TV and the umps got it wrong or flat didn't see it. But Monday night's Packers/Seahawks game is a reminder that "robots!" is still not a cure-all. There will always be a need for experienced, professional, talented umpires in MLB.
