Overrated. .
This team doesn't have a potential star player in their system. Just bunch of question marks.
Maybe Siemens is one player that might become an impact player for the Avs in the future, that's about it.
'Star' players don't typically stay prospects for very long. This team's 'star' players are Duchene, EJ, and Varly.
As for impact players, that depends on how you define it. I would say an impact player is a future top 6 F/ top 4 D/ NHL goalie. The Avs have more than a few of those sorts of players.
Top 6 F:
Michael Sgarbossa - could end up as a #2C or a 2nd line wing if he can't handle the center duties. He has looked solid so far.
Troy Bourke - has potential to end up as a top 6 wing
Colin Smith - long shot, nut boom or bust potential as a top 6 player
Top 4 D:
Duncan Siemens - probably the safest as he should be a top 4 shutdown, may not be spectacular, but solid
Stefan Elliott - highest potential (top pairing PMD), also most likely to bust. Has dynamic skill if he can put it together
Tyson Barrie - Tops out as a middle pairing PMD, bottoms out as a #6 PMD
NHL Goalie:
Calvin Pickard - has NHL starter capabilities, and has looked good at Lake Erie
Sami Aittokallio - most potential of all goalie prospects, looked great or terrible with Lake Erie. If he finds consistency he will be a solid NHL starter
Kieran Millan - I hesitate putting him on here, but he has been great in the CHL and has very good athleticism. Tops out IMO as a backup goalie in the NHL, should be a solid AHL starter.
Now because those players have that talent doesn't mean they live up to it. Of all of those I only expect Sgarbossa, Siemens, Elliott, and Pickard to be 'impact' players at best (I expect Barrie to be a bottom pairing player in the end). Still that is a pretty good number in the system when the Avs have 2 young impact centers (if they keep ROR), 2 young impact wings, a young top pairing D, and a young, very good goalie.
