I think I've come around on replay. I was all for it after the Galarraga and McHenry debacles. But I think it needs to be rethought.
Give the ump who made the call every angle you have,
at real speed
, one time each. That's it, that's all, go make a call. He gets a little more information than he had for the live call, but not so much that we're calling runners out because they come off the bag for three frames.
