The beginning is always the easy part.
It's easy to sell hope at the onset of a rebuild. It's easy to be excited about the new GM, the new coach, the new direction of a team. It's fun to watch the organization pick blue chip prospects at the top of the draft. The hard stuff comes after.
The Brad Treliving regime is exiting the lowered expectations phase of the current rebuild. The kids are getting expensive, the core is starting to coalesce and the club is rubbing uncomfortably against the cap ceiling. Treliving was able to pick his own coaching staff this offseason and by next summer the budget will be clear of the prior regime's last few mistakes (Dennis Wideman and Ladislav Smid).
