You're certainly entitled to your perspective, but imo this is a lame response. The comment you quoted and replied to was in response to a comparison of the Brewers to the Bucks and Packers. Their situations aren't comparable. I'd go into why but if you don't see that there's no point in explaining. You then shifted that to a comparison between the Brewers and other MLB teams, which is fine, except that the Brewers play in the smallest market in either the NL or AL and have the lowest local media revenue as a result. Most of the teams you've listed (Atlanta, Arizona) aren't remotely comparable markets or revenue sources, and yes, revenue matters. Kansas City is certainly closer and as you pointed out they appeared in two WS and won one of them. They also did that in an era where the majority of the larger market teams were poorly run, cutting payroll or both and weren't competitive either by design or happenstance. They certainly weren't dealing with a well run, resource rich behemoth like the Dodgers as they Brewers have been competing with since 2018. Tampa runs its organization a lot like the Brewers, but even after the Bally debacle their local tv revenue alone is 20 million more per year than Milwaukee's because their market is larger. And before Bally collapsed it was 30+ million per more. That matters.
You can call that a lame excuse if you want. I think that's a naive, foolish opinion, but you're welcome to have it. I also don't think you're likely to be satisfied by a WS appearance. If they make the WS this year and lose to Toronto (whose metro population is literally 4 times more than Milwaukee's), for example, you'd be saying the same thing in that series you were last night. And that's fine. Being a Brewers fan is monumentally frustrating. I've experienced since 1978 and was so frustrated I spent close to 10 years trying not to watch or care before I gave up and admitted (again) that I was a Brewers addict in about 2004 or so.
Is it possible for the Brewers to win a playoff series in the current competitive and economic structure in baseball? Of course. Is it possible for them to win a world series in that structure? Yes. But it's a hell of a lot harder for them to win a title than it is for the Packers or even the Bucks, which was the original point of the "lame excuse" as you described it. I don't think that's even an opinion. I think it's a statement of fact which is pretty obvious, but I suppose your mileage may vary.
Have a great day.
Go Brewers.
