I'm legitimately not sure if Willson Contreras understands how baseball works. There's an article with comments from him claiming MLB's lack of consistency in punishing players for HBP. He seriously doesn't understand how no Brewers have been suspended while Cubs players have been suspended twice (and the manager once) in the last two seasons.
Willson Contreras sees a lack of consistency in punishment for the Chicago Cubs-Milwaukee Brewers feud - United News Post
Willson, dude, hitting a guy on purpose (or attempting to as they did against Brandon Woodruff last season) is against the rules. Non-intentional HBP are not. It's really that simple.
It's funny how the Cubs keep trying to paint themselves as the victims when they're clearly the aggressors. Am I capable of understanding they want to send the Brewers a message by throwing at Cutch? Sure, fine, but it'd be great if they'd act like adults and not whine about it afterwards like they didn't just blatantly target a guy.
