Florida is not an exception though. Vegas is the only recent cup winner to not invest in the position and that was because the goalie they had already invested in fell apart physically so they had to make other plans on the fly. Florida, Vegas, Colorado, Tampa Bay, Washington, Pittsburgh, Chicago, LAK all invested significant AAV in goaltending. They were able to chew gum and walk at the same time.
Every recent Cup winning front office has been willing to put significant investment in net. There is no magic front office out there winning cups without investing in net.
