Well, just to stir the pot here i'm going to say that Pittsburgh also had an organization full of "can't miss" or "safe" type prospects a few years ago and not many of them really panned out. Milan Kraft, Kris Beech, Michael Sivek, Colby Armstrong, Shane Endicott, Ben Eaves, Toby Peterson, Matt Murley, Michel Rosival, Ramzi Abid, Josef Melichar, Brooks Orpik, Ross Lupaschuk, Michel Ouellet, Noah Welch, Rob Scuderi, and Konstantin Koltsov. Of these 17 prospects, only two or three had made any significant contribution to the Penguins. In other words, don't count your chickens before they've hatched.
Beech, Lupaschuk, and Sivek looked like sure fire NHL prospects at the time of the Jagr deal, but here we are three years later and Kris Beech is a borderline NHL player, Lupaschuk has played 3 NHL games, and Sivek has played 38 NHL games for 6 points.
