The "never was a star for the team that drafted him" seems a bit unfair. Luongo was traded after 24 NHL games by Mike Milbury and a new ownership group who fell in love with Rick DiPietro; I always enjoy that one of those owners ended up in prison several years later. Toronto traded Rask a year after being drafted, it wasn't like he languished in their system for several years. And comically Toronto thought they had another equivalent goalie prospect in Justin Pogge, so they felt like they could deal Rask to get immediate help.
Kidd obviously didn't pan out as expected, but have you seen the other names drafted around him? John Slaney and Drake Berehowsky directly in front of him. Turner Stevenson, Brad May, Karl Dykhuis amongst others behind him. So it's not as though Kidd was the only journeyman taken in that area. It's easy to pick out "Oh well, they could have taken Keith Tkachuk" but that's a little unfair.
There's not always going to be a goalie worth being taken highly. And sure, I agree that you should take somebody with 1st line upside over a goalie. But once you get out of the top tier of the draft, I think we let the new car smell on some of these prospects imply greater upsides than they really have.
