Long time lurker, but here goes. The torches and pitchforks out for Jack are aiming a little low. He's not perfect, but definitely not the root cause to all the dysfunction either. Management and the people who hire them impact an organization more than your best player does. To that point...
Ownership's influence over personnel decisions on and off-ice makes it all but impossible to assemble a winning team. Imagine being a GM and you're told whom to re-sign, the terms of a contract and then watch as the scouting staff all but purged. What franchise can win with that level of meddling? And what decent hockey executive type would work under those conditions?
Getting rid of Jack seems inevitable, but it won't repair what's wrong. Nor will recycling good or better players for younger ones that have "potential." The team is where they are because ownership doesn't have a clue and remain locked in their echo chamber.
