They've committed to youth, to tank, they'd have to strip the roster and wouldn't be competitive until 2030 or later - it takes that long to rebuild through tanking if you strip a roster down to the studs. Anaheim has picked in the top 10 for six years and still suck despite a top young goalie. Chicago is in their 4th year of tankdom. San Jose in their 5th year. And so on.
Reason it takes so long is you have to be incredibly lucky with a tank (NJ landing #1 twice) and have the right players on board the years you tank. Then you have to wait for those players to develop, and surround them with other young talent. So unless you're both extremely lucky and make no mistakes, you're going to have wasted years. So to get 3 top players, you might have to pick in the top 5 for 5 or 6 drafts.
Take Chicago:
2004: Barker #3, 2005: Skille #7, 2006: Toews #3, 2007: Kane #1, made the POs in 2008, SC in 2009.
That's probably the fastest exit from a tank or record.
Pitt:
1984: Lemieux #1, 1985: Simpson #2, 1986: Zalapski #4, 1987: Joseph #5, 1988: Shannon #4, 1990: Jagr #5, won the Cup 1990, 1991.
2002: Whitney #5, 2003: Fleury #1, 2004: Malkin #2, 2005: Crosby #1, 2006: Staal #2, won the Cup in 2008.
Now what are the odds that a tank will end up with you getting Lemieux/Jagr or Fleury/Malkin/Crosby?
With the lottery, slim and none.
Edmonton
2010: Hall #1, 2011: RNH #1, 2012: Yakupov #1, 2013: Nurse #7, 2014: Draisaitl #3, 2015: McDavid #1, 2016: Puljijari #4, 2018: Bouchard #10, 2019: Broberg #8
13 years to lose in the SC Finals!
