I don't think they will trade Chabot unless it is reactionary to something, like missing the playoffs multiple times, or somehow lucking into another #1 defenseman. They have a legitimate top 4 for the first time in over a decade. Whether Chabot's play has been completely consistent or not, if they trade him they aren't going to have a replacement. Kleven will be a valuable piece, but he won't be that guy.
They have enough long term cap flexibility to keep everybody, although they may have to bridge Greig, Pinto, Kleven, etc.
I don’t see them trading Chabot unless they need to purposely shake up the core.
