Remember that the expectation around here seems to be that a 3OA is a franchise-level player... that is likely, at least a player who can put up multiple seasons in the top-10 in goals, top-10 in overall scoring, puts up 1st line offense combined with Selke defense, or a top-15 D.
Since 1999, 3OA:
Sedin (elite offensive player, HOFer; great at 3OA)
Gaborik (top goal-scorer; what you expect)
Svitov (bust)
Horton (average 1st line forward; disappointment)
Barker (bust)
Jack Johnson (2nd pairing D, at best; disappointment)
Toews (1st line forward, captain, Selke winner; what you expect)
Turris (2nd line C; disappointment)
Bogosian (2nd pairing D; disappointment)
Duchene (average 1st line forward; disappointment)
Gudbranson (2nd pairing D, if that; disappointment)
Huburdeau (average 1st line forward, at best; disappointment)
Galchenyuk (below average 1st line forward, disappointment, though he still has time to hit his stride)
Drouin (2nd line forward; disappointment so far.. pacing 65 points this season, which would make him an average 1st line forward... still time for him)
Draisaitl (1st line forward... can he be a top-10 kind of forward? Maybe)
Everyone after is still too young to make this kind of evaluation, though things don't look good for Strome.. 3 players in those 15 drafts have met the expectation with the jury still out on 3.
3OA isn't a great pick if you're looking for franchise-level players. You need to draft 1st liners too, so that's nothing against that. We'd be lucky to get them, but if we did draft 3OA what most 3OAs turn into, we're still going to need our later picks to turn into franchise-level players. That's the same situation we're in anyway.
