When we don't have cores players, I think, retool is not good option. We should talk about a quick rebuild or long term rebuild.
Quick one - trade all valuable veteran players for mostly prospects and some draft picks and try build team with whatever players the team able to collect.
Long one - Be patient, trade all veteran players and try to collect high drafts pucks and late round gems.
Try to find at least 1-2 very good prospects in a year and repeat 3-4 times until you collect 2 superstar forwards and 2 first pairing D prospects and 3-4 support players to complete the core.
