The top few are usually good, plus one or two later picks per draft. Question is whether those are identified by skill or by luck. Some are certainly luck as they change unpredictably, but say Pavelski, Hoffman, Stone, Gaudreau, Kucherov, Point, Bratt, Marchand, just searching high scorers outside the first round or two...
The Senators and Lightning did some serious drafting.
Other than mostly being mostly small or very small (Hoffman is big) for hockey players I don't know how much they have in common. I'm too lazy to check their pre-draft stats and compare to peers just now.
