My answer is 2 seasons until we are competitive, we will be a tank team next year for sure, definitely getting a top 5 pick and another great prospect as it will be all prospects and very few UFA additions.
but I do not think we'll be in the playoffs in two seasons, I think however that it will be similar to our 2010-2011 season, where we were competing until the last stretch of games and getting somewhat close to a spot. I think in 2016-2017 they will start padding the depth of the team with UFA's.
In 3 seasons we will almost surely be a playoff competing team(5th-8th spot type).
why do I say that? because I think people are confusing what our rebuild is with teams like Buffalo and Edmonton or even what we were in 08-09 for example. The difference between us and those builds is their cupboards were completely empty and they completely torched the team.
we already have been somewhat rebuilding since 2011-2012, by getting Rielly and Nylander. On top of that we already have an NHL starting goalie in Bernier and great secondary pieces in Kadri, JVR and possibly Gardiner if he pans out. Add in some near-ready prospects as well such as connor brown, percy, leivo, nylander, andreas johnson all of whom are looking pretty damn good on the marlies or in sweden in johnson's case.
we're not starting from scratch, we have prospects that are getting close to ready, it's simply about adding a couple top 5 picks these next two seasons and rebuilding the core, not necessarily rebuilding the entire team like EDM and BUF have been doing.
