I think there's more than just that.
The previous summer we had Crawford as a signed goalie, Huet wasn't an option, and the sticking point was Niemi with a major cap crunch. I think the consensus was that Crawford was going to be the backup. As such, we could have made the cost of Niemi a point of contention because all we had to do was sign a starter--which we did: Turco for less.
This summer would have had a different scenario. The cap isn't as contentious, but still an issue, but we only had only 1 signed goalie: Huet. And he's still not an option. It's not that the cost of Crawford could have been as big of a point of contention because we had to sign 2 goalies. We needed a signed starter and backup. Toiveven, Turco, and Richards were all FA's as well, and I'm not up-to-date on Richards, but Toivenen should be as much of an option as Huet is. Turk may or may have not been salvageable. Carruth and Simpson, although unsigned, need more maturation.
I can see the mindset of spending and extra 4-600k to make sure we don't have a big ? in net going forward and have at least one goalie familiar with the system rather than fishing FA's for both starter and backup, or putting someone in net that doesn't belong there (ever or yet). Plus, I'm sure we can make up part of the 600k elsewhere. In fact, Given Craw's last contract, I think that the Salak contract made up 100-200k on it.
