It's not even so much about having faith in them, it's more about the new regime finding out exactly what they have and where they need to improve. But at some point they have to find out once and for all what they have in a Boucher, Matteau and even Josefson and how far away guys like Quenneville and Blandisi (among others) are. Then they can act accordingly. That's why I think you're not seeing PTO's up the wazoo like Lou's last couple of years or patch signings. They want to give what's in their system the bulk of their attention to evaluate them better.
100% nailed it. There's no point in Shero trying to think 3-4 years when he doesn't know what he has on the team right now. There are so many question marks in the organization that you might as well take a season to evaluate them. That doesn't mean tank, it doesn't mean "don't make incremental upgrades" or "don't acquire any forward over 24." It means make sure young players get some opportunities and hope they run with them. If not, have a backup.
