What are some of the worst coaching decisions in NFL history?

If they got a safety they could’ve possibly won.There was still about 20 seconds left.-3 seconds on the safety. Punt form the 20. Let’s say it’s 50 yards with a 5 second hangtime.Thats -5 seconds.Ball is caught at the 30 and returned 20 yards because it’s like a kickoff (on a real punt a 20 yard return
is rare).now they are at the 50 yard line.If the return takes 4 seconds now we have 7 seconds.So you can either throw a quick out than a hall mary or just throw a Hail Mary right there.Unlikely,but it impossible
