I mean they had like a 3 game division lead when they traded him. It was a true kick in the teeth for fans. I would have been horsefeathering livid (ignoring the fact he's a horsefeathers human). I thought the trade made sense for them, though that might be a controversial viewpoint. Even if it didn't make sense, one move doesn't erase everything he built over the last several years. I also don't think not having Hader was the reason the Brewers didn't make the playoffs (at least him alone), and most people thought the Brewers got an above-average return for him. I don't think it makes much sense for a division leader to trade their All-Star Closer in the middle of the season. If they had done that before the season, I think they would be more approving. And I think they got a good return also. The timing would just be very hard to swallow from a fan's perspective.
