Things I Would Like To See Tried But Not Necessarily On A Permanent Basis

1. All balls and strikes determined by K-Zone or a similar computer system. If it is in the box, it is a strike. If it isn't, it is a ball. The home plate umpire would only help determine swings and plays at the plate. Notice, I said I would like to see it tried not that I think it should be implemented. I think balls and strikes have always been very arbitrary, and I don't have the counterfactual to know if this is better than the alternative.
   
2. All major sports have a "the umpire or referee completely screwed up and we have to do something about it" replay system. I imagine this looking somewhat like college football's every play Is reviewed system, but I would like for it to include other blatant bad calls like pass interference penalties. This system would have to be somewhat arbitrary. The idea would be that the call was so blatant that it only takes a single review and everyone knows the referee screwed up, then the call would corrected. I am ignoring the counterfactual problem here, but I think it can be overcome. The system would depend on mutual agreeability between teams. Like with Mauer's fair ball the other night, you give him a double and move forward. I don't think that ex ante (right after it happened) the Yankees would have disagreed with that, especially if they knew the same would be done for them. Again, I just want to see this and admit it might not (probably won't) work.
   
3. I would like to see a college football playoff system, but I think it is like the above things. It might work, but I don't think it is guaranteed. (Listen to this possibility, Virginia Tech versus Miami in the BCS championship game. I don't think Florida or Alabama is going to lose twice. Texas didn't impress me last night. I know Virginia Tech will screw up. But imagine the possibilities. This is why I am unsure about the playoff system.)
