I think you are in a small minority, but I respect your opinion. I do not think it adds more commercial time. There are a designated number of commercials per half and once they use them up, they stop taking commercial breaks. So I guess a replay that occurs after the commercials are used up would add more time, but I do not think any more than 5 minutes is added to the average game, probably less. The same goes for baseball, ultimately you add only a few minutes to the game, with the result that the integrity of the game is improved. Most games would not even have a single call reviewed so it would generally be inconsequential. I am also in favor of fully automating ball/strike calls, but I recognize that is still probably about 10-15 years away from being implemented. I strongly believe that it is inevitable, it is just a matter of time to refine the technology, get it on all broadcast TV, and then have a blown call get lots of media attention. The Joyce call will ultimately result in more replay, public opinion has been in favor of it ever since.
