Technically, Crawford wrested the starter's position from Turco in 2011 (much like Niemi from Huet the season prior), and Darling saw much more icetime as a backup prior to this season that Crawford did by the start of the 2011 season. Case in point; Crawford between 2005 and the start of 2011 played 8 total games. Darling, prior to the start of this season (2014-start of 2018) played 75 games. Hell, even if you throw in Crawford's 57 games "as a backup" in 2011, Scotty still saw more icetime before taking the starter's mantle.
So, in my
opinion, Crawford's 1st starting season was 2010-2011, and there was very little book on him prior. Meanwhile Darling had a lot more made of him prior to the start of this season. It wasn't until 2012 that Crawford's tendencies and whatnot were fleshed out by the rest of the league, while there was ample time to get book on Darling prior to the start of this year.
Now, your arguments about Waite are rock solid though
. I think he's gone a fantastic job and maybe there is something to him being better than whomever the 'canes have, but I think a lot of Scotty's bad year this year thus far and Crawford's excellent year this year thus far have to go to the netminders proper. But I do fell that we have to see where Darling goes after this year to say whether or not it's a fluke this year (much like Crawford's 2012 year).
