You didn’t read the last paragraph?
He didn’t build an abomination. He made mistakes like every other GM in sports does. He also did enough to get the team to a Final in 2019 where they had home ice and were the better team. Unfortunately, the players and coaches screwed the pooch. That wasn’t on Sweeney (except they should have had a better option than Backes).
In 22-23, he did everything you could possibly ask for from a GM for a contender. Having a historical season and he adds Bertuzzi, Orlov and Hathaway to a team that was already setting records. Again, the players and the coaches F’d up and let it slip away.
Lots of things Sweeney could have done better, but he did enough for them to win 2 Cups in 4 years, it just wasn’t to be. It’s easier to blame the GM than it is to blame all the players.
