I think Dallas and Colorado have a number of similarities: they both currently stink, have lottery draft picks in 2017, have lousy defensive rosters, poor forward depth, questionable goaltending, lots of missed high draft picks over the past 6-8 years, a few proven high end players, and one recent anomaly season that made them look much better than they really are/were. Lots of similarities there.
I suppose Stars fans and Avs fans could argue back and forth about who has the better prospect pool, but I suspect that would just be an exercise in who overrates their prospects more.
To me, the two major differences between the two organizations that could quite likely override the current state of the two prospect pools are : Nill/Hitchcock vs. Sakic/Bednar in general, and trade deadline/asset management philosophy.
Both teams were out of the running this past season. Avs did nothing to address their future, while Dallas made 4 trades netting 4 assets under 25 years of age. (IIRC, the Anaheim 2nd round pick they got in return for Eaves, turns into a 1st round pick if Anaheim wins game 7 against Edmonton.)
