How many 4 goal comebacks with under 6 minutes have you seen ever? It's not 1 in 100, it's 1 in several million. If cou vant maintain possession and score within 2 minutes, odds becomes 1 to several billions. The other team knows how much time is left. If you stay 5 on 5 and lose possession, instead of icing it, they start just passing it around if they hain possession and kill so much time you have no chance either.
A few 3 goal comebacks with empty net and 4 ?instead have happened including during the playoffs.
Odds are in billions anyways. If you can't maintain possession with 6 players, what makes you think they would have been able to with 5?
No way are odds so bad even for a 4 goal deficit with over 6 min left.
When I was a bantam age player I watched a Midget triple A tournament in Vernon and the one squad came back and tied a 3 goal deficit with 1 min left (60 sec, 10 sec and 1 sec). I remember Calgary doing a 2 goal deficit comeback with a minute left in Iginlas early days in Calgary in the late nineties. Didn't Buffalo have a 7 goal first period in the regular season and a big comeback win against Pitts around that time; pretty sure NYR had a huge first period goal total too. Yes it's not likely but it's not impossible. And the key is using your momentum while jumping on the leader while they're asleep. Things can happen quick even in this sport. Then you use two lines mostly riding your first line for the final 2 minutes while employing set plays. Anything else is careless and taxing on your star players to the point of ineffectiveness due to fatigue.
I'm pretty sure I saw a game or two this playoffs with McDavid and Draisaitl being practically ridden for the final 3 minutes or more and it not working. Even superstars lose their ability to change a game after about a minute of play (normal shifts being anywhere from 35 to 45 sec).
