I don't disagree, the officials are opening themselves up to a whirlwind of criticism if they won't decide between right and wrong when the video evidence can be used to "quickly" determine the correct call. How will a Coach's Challenge be handled? "Well it looks like you were right Coach...but not right enough to overturn the incorrect call of the official." Too much gray area, they should get rid of the Coach's Challenge and self-police.
What they needed to do was get out front and clearly explain their policy before the season began to coaches, fans and especially the broadcaster so they wouldn't break down video to the micro-second looking for these "gotcha" moments that inflame everyone.
First weekend down and they're already in damage control mode.
