-Chabot's name was never in discussions, Ottawa was absolutely not willing to make him available.
-The inclusion of Ceci had two reasons: 1) He's a 23 year old Defenseman who the Avs could say "We acquired a defenseman"...basically, he's young, he still has some potential (but is coming close to not harnessing it), and 2) it'd be the "PR piece" of the trade. The real crown jewel of the trade would've been White and Ottawa's 1st. With White, the Avs would've really had the draft board opened up, because they'd have him, Jost, and MacKinnon as Center options next season (if Jost actually makes the team). The Avs could still take Patrick, or maybe then they like Vilardi/Tippett/etc. and want to move down. The point being that White would've filled a big-time hole as a great #2 Center for the team.
-Ceci is the most likely defender to be exposed in the Expansion Draft (from my understanding). It doesn't sound, as of right now, that Phaneuf is wanting to waive his NMC, and my understanding is that the Senators don't want to lose Methot either. So that leaves Ceci out to dry. This is absolutely a deal that could be re-visited in the off-season, but before the Expansion Draft.
