"full of young players" sounds like an exaggeration, they have maybe 4-5 young players and only 2 of them are high picks and one of those players (Byfield) doesn't look good
Again, same applies to Washington. You can make a point Ovechkin is still their best F, Carlson still their best D but young blood energizes the lineup, it doesn't have to be all Stutzles and Bedards.
Now, down to numbers, Anderson, Clarke, Spence, Byfield, and Laferriere (who is 3rd on the team in scoring, high pick or not) are all 25 or less. Maybe you could add Turcotte to that list as well. In which case it would make it 3 high picks although again, not sure if that's relevant.
Out of the impact skaters, only Kopitar and Dannault are over 30. Now "full of young players" might have been and overstatement but the team basically doesn't have big names that are past their prime unlike so many other struggling team people expected to be better.
