I'm not a huge Pro Sports enthusiast b/c 99% of the players do it for a pay check now, not for the love of the game. They never had them back in the day, so why now? Then again, if an ump or ref screws up a play and the whole US sees it, they should do a replay of it. Kind of like the perfect game the kid pitched until the 9th inning when the ump screwed him a few months ago. IDK, it is just all ridiculous anyway. If you get instant replays then more players will be fighting w/ the umps for being dumb and this and that.
