This is year 1 of this rebuild & lots can happen, but they should be accumulating assets that can improve their team to be a cup contending team at some future point. Given a choice between Pageau & Tierny, it's no contest, I would keep Pageau. But in a yr where they are rebuilding, if they could get a 1st rd pick for Pageau than I think they have to pull the trigger, especially if the pick is for the 2020 draft which so many are calling a great draft. Three first rd picks & potentially 4 2nd rd picks would be awesome for this franchise regardless that some of the players picked might not be NHL ready for 3 yrs or more, others likely will be. And it might also give them that extra pick to go after potentially the best goalie in franchise history.
I'm all for moving most of their UFAs & a couple of other guys, but you can only move the players that there is a market for & Ottawa has a few players that may not have any value or market such as, Ryan & Boedker. They may have to wait until the end of the season for Boedker's contract to be done before getting rid of him & they may have to buy out Ryan at some point. But there could be a team going into the playoffs that could use any one of these UFAs like Boro, DeMello, Hainsey, Ennis, Namestikov, Pageau or Anderson. Next yr it might be Anisimov, Nilsson, Tierny, Duclair, Chlapik & a few others that might be available for trade. They need to keep accumulating as many good assets as they can for drafting or trading for good young players that could have a future with this team & this is the yr to do just that.
