Some fans don't like it. It's sell, sell, sell all the time. Flip every asset for younger ones, until you hit that perfect moment. The majority of teams, most of the time, don't work that way though. Buffalo lost both Briere and Drury on the same summer day in 2007, but they didn't flat out suck until.13-14. Maybe that's just bad management in Buffalo, because they're still rebuilding almost a decade after bottoming out, but most teams don't want to be bad.
After this year, with Lucic and Monahan gone as UFAs, that's an extra $11m+. Re-sign Huberdeau if he'll stay, use the open space wisely, and you could have a decent team again. Maybe not a contender, but there are only so many true contenders any given year. Most playoff teams are hoping things fall their way for a few weeks. And if you happen to get some playoff game revenue, it's a nice little bonus.
This contender or nothing thing is unrealistic. Where are you likely to end up after you rebuild? Back in the middle, where you were before you rebuilt. Or you get good, but not quite good enough, because there are only so many players to go around. You end up as perennial bridesmaid SJ. Just a laughingstock due to how pathetic they were.
