re: The safety is taking advantage of the rules
It was brilliant strategy. With just under 2 min, I called the safety as the play to make if they had a 4th down.
I agree. It seemed to catch the 49ers off guard; it took them a bit to remember they had to tackle the guy or get him out of bounds.
I wonder how long a team could form a scrum-like ring around a kicker and keep him upright and unable to be tackled?
