Clubhouse morale post-deadline is a big concern of mine too, which is why I was encouraged to read this comment by Willy last night, and why he (and the others you mentioned) are so important in that regard:
"I don't really pay attention to that, but I'll say that I take it like a compliment," Adames said of the Brewers not bringing in any new players to the offense via trade. "I feel like they trust the guys that are out here and we do, too. We're trusting ourselves and we have a pretty good team, a pretty good lineup and we can do a lot of damage. We just have to be more focused and try to do our job and try to do our best, and we can be great."
