Because teams do not start rebuilding from the same place. Detroit's rebuild began at the end of a very long playoff streak where they fought to get into the playoffs until the very end, did not trade away any aging talent, and were left with a barren roster and empty prospect pool. Seems silly to me to try and measure that up against Montreal. You earlier replied have been rebuilding for only three years of missing the playoffs. But Montreal did not start in anywhere near the same position. Kotkaniemi was drafted 3rd in 2018, Sergachev 9th in 2016. Montreal traded a top goal scorer in Pacioretty for Suzuki who was 12th in 2017, and they also missed the playoffs in 2019 and drafted Caufield at 15th. If you want to say Montreal has only been rebuilding for three years, is it then four year failed rebuild, two fluke Covid years, and now three more years of rebuilding? These two teams simply did not start 'rebuilding' from anywhere near the same position.
