I don't buy Bud Selig's argument that replay would take up more time in baseball games' already lagging pace. Managers and umpires already slow things down when they argue these tough calls, as do umpiring teams when they consult on the field in an effort to get the calls right. So instead of these primitive uses of time, we'd instead get an official looking at the replays, in an area away from the ballpark, and making the right call.
Is there anyone out there who doesn't want replay in baseball?
