As a reasonable fan, I like it. I am always frustrated at the lack of replays for controversial plays. At the same time, I see that there could be potential for trouble by playing them. Comparing baseball to football and basketball is not valid in my opinion because anger at/heckling of the ump is more acceptable and ingrained in baseball etiquette. It also tends to be quieter at baseball games as compared to football (because of the consistent energy of the game) and basketball (because of the enclosed arena factor), so heckling is much more effective. Overall, I'm glad we'll be pushing the envelope.
