I voted for Hackett solely on the premis that decent goalies are hard to come by these days and its nice to know we have a plan for the future.
I have the exact opposite view on goaltending. It's not like 20-30 years ago, where only a select few were truly quality goaltenders... You can find a decent goalie now in so many ways it's crazy. Sure it's a position of importance, but it's no longer a position of much value.
I think a lot is lost in translation between the pro-goalie and anti-goalie camps. I'd have to say that what the pro-goalie camp usually says is the right reasons for the wrong conclusion while the anti-goalie people have the right answer for all the wrong reasons. Ultimately, there still are elite talents in net that are just better than what other teams can hope to have. These goalies are capable of stealing games on their own and as an individual are quite rare and valuable to have. However, the difference between an elite goalie and a decent goalie isn't what it used to be. Maybe a decent goalie gives up bad goals on occasion, maybe they don't steal a game when the rest of the team is slacking, maybe they have slightly worse stats than those elite guys. However, those decent goalies are still pretty good. They're not consistently a liability. You're not winning because of that decent goalie, but you're also not winning in spite of him. But there's a ton of those decent goalies. Almost every team has at least a decent goalie on the roster. He's a guy that's good enough.
The reason why goalies aren't exactly hugely valuable is because almost everyone has one (or can get a passable one) and each team only has room for one starter at the position. Even the starter/backup system itself encourages this behavior. This offseason is a bit of an anomaly in goalie values as there's more teams than usual who need goalies while the supply is pretty weak this year. Most years there's a guy like Theodore who is simply out of a job because no one still needs a goalie right now, and not because he's some horrible liability.
I think he's the most NHL ready goaltender we have, and I don't think he's that far off. That's no slight to Dumba, Zucker or Bulmer; but I think Hackett is at the very least above average and I'm still not sure the others are going to really be able to shine at the NHL level.
