You could see in the last 20 mins that both Rangers full backs were getting more and more of the ball because we had retreated into our own penalty area and it was only a matter of time before one of their crosses landed lucky. There is such a thing as having too many defenders in your box sometimes.
Did Mugabi just miss the flight of the ball at the 1st goal or did he actually duck because he thought the ball was going behind and didn't see the player behind him? Not sure on that but yet another basic error. Who knows what would have happened if they hadn't scored from that.
