It’s very rare for a goaltender to be drafted early in the draft. No goaltenders are expected to go in the top ten of this year’s draft, or really any NHL draft for that matter.
It’s safe to say the Blackhawks won’t draft a goaltender third overall this year. Assuming there was a valid candidate to go that high in this year’s draft, would the Blackhawks need one?
Probably not; Corey Crawford, when healthy, has been very good over the last several years. Goaltenders typically take the longest to develop of any position, so it would likely take a long time for any potential candidate to even make it to Chicago.
