Great article in the Athletic by Dillman.
When possession was throwing pucks at the other goalie, and there were competent defensemen, and they had C's that you knew would do what they needed to do, Quick's style of play worked very well. As the team has changed, as defensemen have disappeared left and right for various reasons, as the 4C went away, as the 3C went away, like any goalie, Quick's game has gotten exposed. Other teams find the weakness, and in Quick's case, it's the over aggressiveness. Since he's not quite Hasek, that aggressive play depends on others.
When he's on that fine line between athlete and goalie, he can be amazing. When he veers into being too much of an athlete, without the quality skaters in front of him to back him up, it can be a mess, and not just last year. If he's too much of a positional goalie, that's not who he is as a player, and it doesn't even look right. That's the question. With the age, with the injuries, can he be, how much longer can he be, the athlete he needs to be? If he has to change his game, is he Jonathan Quick anymore?
It's crazy, but you don't appreciate guys like Fraser, Stoll, and even 2014 Richards to some degree, until you can't find a way to replace them, for years on end. Lecavalier was a fun option, but very specific. If it meant he was back on the left point on the PP, never hitting the net with booming slappers, would we gladly take Stoll back? Tough enough replacing high level talent. The role players have to be the right guy at the right time too.
