It actually isn't, in the land of the NHL. There are virtually no good teams that get to that position without hitting on a few of their own very high draft picks. It's almost impossible to become a true contender without a few guys that were drafted in the top ten in their year. You can get really really lucky, like the Red Wings did hitting on Datsyuik and Zetterberg, but that will never be repeated again.
In order to get good, you almost have to go through a period of time of being really, really bad (and not trading away your picks). Then you have to hope you hit on your picks. The Flyers never seem to do that all that much, and hence they have been mired in no-mans land. But Chicago will likely rebound nicely in the next few years, with all of the picks they've had. Of course, like we got lucky getting Crosby, they got lucky getting Bedard.
