fine. Crawford is good. Better than Bryz or Howard or Schneider. Lets start with Crawford. Whats wrong with him? Jonathan Quick. Fleury to an extent. How many Vezina level cup winning goalies are there? How many have been allowed to walk in their prime?
First off, Crawford. Have you paid any attention to Chicago over the past year? He hasn't played since December and there's pretty significant questions regarding exactly when he will be able to play again (just returned to practice today) and if he can ever be that goaltender again. Ultimately, though, you're right in that this is one of the better long deals for a goaltender in the NHL, as it expires after next season and only takes him until age 36.
Jonathan Quick is about the best case scenario for a long contract, and even his has involved him fading from his Conn Smythe-form and a season basically lost to injury. He also still has five more years on his contract, all the way up to age 37, so there's significant concern it could go poorly later. Not to mention it's also a contract that is no longer legal under the current CBA, since it used its length to suppress the total cap hit.
Fleury's contract was such an albatross that Pittsburgh had to pay to guarantee that Vegas would pick him in the expansion draft. For the bulk of his contract he was a sieve and the biggest individual reason the Penguins didn't win more Stanley Cups. He had five different playoff campaigns with save percentages under 90%It wasn't until Matt Murray entered the picture that they were able to return to winning championships.
So we have Quick and Crawford as relative success stories (both involving a season lost to injury and with Quick's deal barely half over and plenty of time to change into another cautionary tale) and Fleury as another example of long-term investing in a goalie going poorly. It's pretty clear at this point that the bulk of the goalie deals over the past coupld decades have shown that signing up long-term to a goalie is not a wise investment and it has huge potential to backfire.
Also, peak Schneider was better than Crawford and arguably Holtby. The fact you're diminishing him isn't helping your argument.
