Huge difference between a squib and kicking it short of the goal line. These kickers are perfectly capable of placing it around the 5 if they want to, and you should absolutely trust your special teams to bleed 5 seconds and stop them well short of the 40 more than you should trust your defense to stop Mahomes, Kelce, and Hill with two plays. At worst, they still only have one play to get into FG range.
Even so, you have to have triple coverage on Kelce and Hill. Mahomes only has eyes for them with that little time left, and even if another guy gets open, he's going to take an extra moment or two to find that guy or force the ball to one of the first two.
