Instant replay in sports (3)
I think the question regarding instant replay in sports is not if it'll become more widely used, but how it'll be implemented.  There's no doubt that human referees make mistakes.  It's perhaps a little naive to think a mere mortal can make an important split-second decision while under immense financial and spectatorial pressure, and to do so flawlessly, every time.  I think we should accept that fact and do something about it instead of getting angry and blaming the refs for bad calls.  The way the NFL currently uses instant replay is a little annoying at times, and certain coaches appear to use it as a momentum-stopping tactic, which is smart but not what it's there for.  But at least it's there as an option to challenge the calls that are the most obviously wrong.  My prediction is that most, if not all, sports will soon adopt some sort of instant replay.  Or else they'll start utilizing error-proof robotic refs.  One or the other.  Because honestly, something like the strike zone in baseball is a scientifically measurable thing.  Nothing that's measurable should ever be left up to the opinion of a lowly human. #sports
