Hockey is 60 minutes just like football. However, it feels longer than that beacuse there are, count them, three 20-minute periods.
Now, if one were to watch a college basketball game that only has two 20-minute halves and then turns around to watch a three 20 minute per period hockey game, they might feel like the game is 20 minutes too long.
Now hockey is and has always been played in three 20-minute periods. With that said why in the world is it necessary to have intermissions after every period, even when heading into overtime?
It is too much analysis and not enough game. Keep the flow of the game going and stop having these intermissions between all the periods.
At the very least, omit the intermission between the third period and overtime.
And the intermission between the first and second overtime if the game reaches that point.
