Right now this team is a minimum of two years away. Let Holland assume the role of President and horde as many draft picks and cap space as possible while GM, to give Yzerman a nice statting pallet to work with to start the 2019 season. I trust Holland and staff's ability to draft players and will have some nice high picks in the next couple years along with a wealth in the later rounds to develop.
I'd much rather use any available cap space on taking flyers on some reclamation free agents for a year and see if you can flip them at the trade deadline. In a couple years, we'll be in much better shape cap wise as well to make a big splash with free agents and hopefully some solid prospects and current roster players available to possibly flip in making a move like acquiring a Trouba type player.
