A couple thoughts from this trade...
A lot of people (I believe in the old Off Season thread) were saying that Daley would easily replace Oduya. Better offensively and comparable defensively...boy was that off. Sad to see that Daley didn't work out and didn't live up to the expectations of some since it would have made this team better, but it just wasn't there and he wasn't a fit.
This trade is a downgrade when it comes to the player that is going to be on the ice. Scuderi will provide some things that Daley doesn't and maybe that is okay in the #6 spot but this is an overall downgrade. Speed is going to be the biggest difference and Daley was finally using his foot speed a bit more as of late.
The real reason for this trade, atleast I hope the real reason, is likely the cap space that it frees up. It may allow the Blackhawks to make a trade or get another good long look at Gus/Svedberg/etc. It may allow them to eat salary on a Bickell deal and be okay with it. Hopefully this deal is to allow things to happen more freely in the future so that this team can improve.
