This is what I'm leaning towards as well. They've replaced these two guys (sort of) with lesser picks and made some cap space, now they can let both of these guys go, get a couple of picks from the Blues, and work with a 2nd and 3rd rounder in this draft instead of...well, nothing in this draft.
We also needed to make some changes to that blueline after last years playoffs. Ceci may not have been the biggest culprit, but having him here did mean that we can't improve the slot he was in. Now, Ceci is gone, and we might have some assets to actually improve on that 2RD spot. Maybe.
