I am wondering if the decision to rebuild and call it that publically was related to knowing the Hart situation was coming down the pipeline? Would they have been buyers at this deadline if Hart was never involved?
No, this goes back to before Briere was hired and Torts came out and said this team was 4-5 years away (i.e. as long or longer than his contract). When Briere was hired that spring, he made it clear he was on board with Torts in that a rebuild was required, they weren't going to tank, but they were going to focus on adding young assets.
The problem was CF and Scott, the G trade should have been followed by trades of Sanheim and Risto, no TDA deal, etc. But Scott would never sign off on a rebuild and CF knew a rebuild meant he was gone.
Briere traded Provorov and dumped Hayes, TDA, Hodgson and Connauton, let Braun, Lemieux, Willman walk, clearing more contract slots. Only additions were Poehling (24), Hathaway (2yr deal), and Staal (1yr deal).
Added 1st, (2) 2nds, 5th, 6th rd picks, Grans (21), Rizzo (22), Walker (29), Peterson (29).
Walker is a trade asset, Peterson simply a salary dump.
