So the NFL rule is different than the college rule for kickoffs. In college you can fair catch the KO and get it at the 25. In the NFL, if you fair catch it you get it at the spot of the fair catch. So the Chiefs could fair catch lose no time but get it at the 10. Let’s say the run it that wastes at least 4-5 seconds. So let’s say their at the 30 now with 9 seconds left.
On first down from the 30 you mug everybody just mug them and keep two deep safeties in case someone gets lose. Ball either gets caught for 15 yards or we get a 5 yard penalty. So there is now either the ball at the 50 for a 68 Yard FG or a Hail Mary into the end zone
