Lol, what you presented is a young inexperienced team without generational players at any position. The type that if they make the playoffs get the brakes beat off them
There is no contender that has players like 25 and younger Byfield and Kupari as their top 2 Cs, early 20s Clarke as their #1D, early 20s Spence as a fixture on their second pairing, and a goalie who has yet to play in the NHL as a #1 combined. It takes far better player than them years to get there, especially defensemen and goalies. Doughty and Makar are the only D that got to that level relatively early and good as Clarke is he's not in the same league (literally) and may easily top out as Rielly
Edmonton with McDavid and Drasaitl going on almost 10 years each still hasn't figured out the playoffs, just like Toronto with Matthews, Tavares and Marner. Any of those are better than any player on your roster by far even factoring in the most optimal development curves
It took Tampa until Hedman was in his 30s and Stamkos, Kucherov, Point were grizzled vets, a better goalie than any LA had in their history going on his 7th season, on top of adding every grizzled veteran they could get to break through. MacKinnon took 9 years, Capitals took a decade. The prospects you're penciling in would all need a Tage Thompson like development curve and several years to learning what it takes to win a round to even be in the conversation
