Over the last 4 years, he's 29th out of 44 goalies for save% (minimum 100+ games played) with only one season above 0.910, which was 3 years ago.
No doubt he's been really solid these playoffs, but the last 4 years he's been playing at a similar calibre to guys like
Reimer, Bernier, Mrazek, Koskinen, etc, while still regularly being referred to as the best goalie in the world by analysts. So I agree, he's definitely one of the big ones who will be overrated, unless he can turn back time on a 4 year trend which is like a ~200 game sample size.
Maybe the most interesting one though is Danault, because he's a UFA. I really have no clue what his next contract should look like, especially in a league that when it comes to forwards, mostly pays the big $$ for offensive numbers rather than defensive ability.
