Reversed HR question

[JJ]

Aside from getting an occasional call changed, the biggest thing that replay will do to the game is slow it down. That's not good when all we've heard for the past few years is "speed up the game....keep the game moving.." I guess when millions of bucks are on the line that replay is more important.
I wonder how many "challenges" (if you will) will be allowed per game, and where that umpire will be that reviews the replay? I can see the UIC saying, "I'll be right back everyone...you folks at home watch a few more commercials - I have to look at a tape and maybe make a quick pit stop "
They'll have to prove to me that it's a valuable, workable tool before I'll say it's a good thing.
