I mean, by this philosophy - you should only be concerned with winning if you think you have a shot at the world series. "What's the point of winning the division? We're going to lose right away in the playoffs."
Look, I get that this is a rebuild. However, you can't just lose 95 games every season up until your "pre-determined contending" season and be under the impression that "Welp! Suddenly we're going to be great now because it's 2020! Remember how everyone promised we'd be good in 2020? Well, here we are!". It's not just going to happen overnight.
You need to see signs of growth from the team. Seeing them find ways to win is a big part of that. The rotation has been quite poor, but Cease is on his way up and Kuechel (or other outside help) is an option. Eloy and the young players should only get better. If I believed this team was as good as it was going to get in 2019. Sure, I would agree that we're going to hit some mega rough patch at some point. However, there's real concrete reasons for cautious/realistic optimism here. Wishing for .500 and some competitive baseball isn't asking for the world.
I'm not one of these guys who actually thinks we're going to be in a serious wild card hunt come September. However, to suggest that we should still (one year before we all think we're going to be a serious contender) be disregarding winning/losing entirely is just silly... That mentality has to end at some point.
