Good article in the Athletic that goes on about why teams shouldn't roll up the Brinks trucks for goaltenders. If you really look at the numbers it's the one position in the NHL where teams aren't getting what they are paying for.

I don't believe you just let your best goaltender walk when he's up for contract renewal but a GM needs to have some restraint when it comes to allocating money and term to the position.
