I didnt say it would change the sport, but it would do better. The NHL playoffs could start right after the superbowl, when sports fans are starved and have nothing to watch but mediocre nba regular season and finish mid march before march madness. Also, the NCAA is somewhat sane, and they have their games on during the day mostly, leaving time for the NHL to have the premiere time slot which is like 9pm at night or later est.
Of course that means having less games, or starting the season early - and it already starts pretty early, so it would never happen. Owners want more games. But the NHL and NBA could benefit from less games, which is why the NFL does so well. Each game actually matters.
