So what this is saying is that we have not drafted/developed well, especially at the forward positions, and that our core is getting older.
Stop the presses, I wish someone, anyone, on this site had made those observations before.
Also, as pointed out it is a deceptive stat, much like the 'trusim' that a team can not devote so much cap space to 4 or 5 players and win. EVERY team who is in the playoffs, and especially the teams most likely to win a cup devote around a third to forty percent of their cap space to a handful of players. Same here. The better teams are older, the crappy teams for the most part are young.
But as said there is a minor point to the idea, namely we should have drafted and developed better to round out the team. But again, even that minor revelation is no revelation to anyone who is not a moron.
