All it takes is one run and the label is gone. 2007 is missing from this poll because Ottawa went to the final? Still lost though. Washington was in this conversation and then they won it.
Things need to go your way and it takes time. Look at Colorado, Landeskog drafted in 2011, MacKinnon in 2013, Rantanen in 2015. So they won 11 years after drafting their captain, 9 after their top forward, and 7 after adding another huge piece. And they still didn't round out the team until getting Makar then unloading Duchene for basically Girard and Byram. Hell they finished LAST overall in 2017. Toronto would need to retool slightly and still have time to get rid of the label.
San Jose should be here as well. Great team for years, nothing to show for it.
