Only one team a year wins the cup vs 10 teams in a top 10 pick. Last 5 cup finals, vegas is the only team that doesnt have a player they drafted in the top 5. Vegas has worked to acquire top 5 pick talent in their prime though.

Top talent is typically found at the very top of the draft. You either trade for it with a high acquisition cost or you draft it yourself. Typically you have to draft it yourself. You still have to draft decent outside of the top 10 or do good trades but there is a pretty clear correlation in these last 5 finals and having been bad enough for a top 5 pick for atleast 1 season. Even our finals appearance came after having a top 5 pick. Granted we used that top 5 pick as a trade for a different top 5 pick but without Jones there is no RyJo. Without RyJo there likely isnt a cup final.
