Stewie Griffin
What the deuce
Savard was also a RHD which tends to be viewed as more valuable, and the most targeted RHD (maybe even defenseman in general) at the trade deadline. The only other relevant RHD that was traded at that time was Montour who got a 3rd.A 2nd rounder is the minimum here. He's actually better than David Savard, who fetched a first (with huge retention) last, and the Canadiens will absolutely retain here.
This year there are lots of defenseman worth more than Chiarot who are upcoming UFAs. Leddy, Giordano, Lindholm, Rielly, etc. I'm not saying they all will be dealt or even shopped around, but there shouldn't be a bidding war for Chiarot just given the fact there's more options for teams to choose from.
