Is this a trick question or something? Player values are always in flux, for example this season Kadri's value has gone up, Marner's value has gone down, Campbell's value has gone up but nobody knows for sure where we'll be one month, two months or three months from now.
If they want to sign him it will be for the same reason any player is signed - they figure it's in the best interest of the team to do so.
So if we can't get Campbell, no problem we'll just get someone else? That's worked our well for us over the last couple decades, hasn't it?
But perhaps I'm missing something, who are the goalies that you figure would be available to us this summer who you consider to be on Jack's level or better?
