I think the biggest issue is more with the fans and being sold a bill of goods (#1 picks = high price). Its equivalent to your stock broker selling/advising you on stocks then them being overvalued and inevitably having to sell them next to nothing.
(Issue 2) Path of development:
People on these boards got laughed at for sending down RNH or Yakupov. Getting caught up in politically correct terms such as first overalls never get sent down. These lower leagues continually develop the player because there not a finished piece at 18 - far from it. Sometimes even Hall you wonder if a player could be sent down to the AHL after the draft had he benefitted from a good developmental system.
There was issues with teaching defense that many of the coaches have talked about.
(Issue 3) Leadership leading to Growth & Maturation
All high picks - never sheltered, never mentored, never having good decent leadership to guide them through.
I always thought you need veterans but your most talented veterans to be leading your young players on and off the ice. Shawn Horcoff, Ethan Moreau were nothing short of horrible mentors.
(Issue 4) Makeup of the team
Sometimes you can have great players but character or personalities or work ethics dont relate or mesh well.
The composition of just making a team out of great players doesn't inevitably mean that you created the right mix or attributes of players.
The untouchables are inevitably the most valued based on flexibility and ability to offer intangibles such as leadership, character and positive influence on other players.
None of us truly can say who is an untouchable at this point the positive affect of Maroon may make him more valuable then a Eberle.
To many people put to much stock into points/goals/assists and whether your giving that player to much leway because of talent over doing fundamentals right. As one coach told Ovechkin we want you to sacrifice goals if it means being more of a complete player. Its buying into team concept and player/team identity.
I will leave out who I feel is untouchable besides unquestionably Mcdavid - the others I don't know.
