Brewers don't cheat by stealing signs, they use the old metrodome trick of blasting the A/C out during the Brewer's at bats and in during the road teams at bats 🌬
There's more smoke around the Brewers than that. There was a story that came out right around when the Astros story broke with an anonymous survey among players that cited the Brewers along with the Astros and Rangers as the team most players suspected of sign stealing. There was also a story that after getting shelled in the first series in Milwaukee (25 earned runs in 25 innings), the Cubs switched to giving multiple signs to pitchers even when there was no runner on base and they gave up significantly fewer runs in Milwaukee going forward.
I fully admit that my irrational hatred of the Brewers that we established upthread could be clouding my perception here.
