it is a good rule change, the game is played like that internationaly(my self included, amateur league), it will speed things up a notch.
i have a problem with the video review system. coaches should be granted 2-3 challenges to kick the review, and be refunded if their claim is legitimate.
the refs are abusing the system, going to review on a sure call, just because some of the players complained, sometimes just to get their coach a free time out. and the game is killed in the last two minutes in that fasion, there are like 4-5 time outs and 2-3 reviews.
