The fact remains - he has been GM almost 2 calendar years. He’s accomplished nothing since that time, other than Michkov. Using the word rebuild bought him time, but not when you only find a way to bring in one potentially high end player.
I wouldn't say he's accomplished nothing - it might not be things you like, but he has done 'stuff'.
To your point, though... what has he accomplished?
a - moving out players he didn't think fit what the team is trying to build
b - picking up assets by using cap space
c - eventually trying to free up cap space
He's done a lot in less than 2 years, actually... though I'm not sure it's all part of a coherent strategy. And he has definitely sold low on a number of assets and gotten little in return. Also did not extract value from swapping 1sts with Edmonton.
You might say he has a bias for action lol.
