I realize he's only the second goalie taken in the first round of the NHL Draft over the last five years, but over time, some have been successful.
While it feels to some like drafting a goalie in the 1st round never seems to go well, I found some 2013 stats about goalies drafted in the 1st round from 1988-2008.
Out of a total of 44 goalies picked in round 1, 15 of them currently play in the NHL and 17 have retired - 32 of 44, or almost 75% "made it" at some level. About 14 were starters in 2013 and/or long time NHL starters, including Brodeur, Schneider, Luongo, Rask, Varlamov, Gigure, Kari, Ward, Bernier, Fleury, etc.
Granted, many more drafted in rounds 2 and 3, so first round isn't quite as statistically high to net a long time starter, but again, statistically, its a gamble, but not so much if you believe they are a player you need (and boy, do the Stars need another goalie of the future) but nowhere near "never, ever, never, ever" territory.
The "never" part is really typical fan over reaction. I am quite sure the teams that drafted those above feel okay about those picks (in general, each one has its own story) Then again, each current prospect has his story.
Dipetro may turn out to be equal or better than Otter, who knows. Nill had a decision to make, and he made it when it counted. Pretty easy to second guess from the upper deck. I mean, its not like second guessing LV for letting Methot go for such a low price.....although, both sides of fans are actually doing that, too.
