Idk if people saw Zolak&Bertrand today, but when they talked with Mazzulla which is their regular weekly segment, he just sounded like a different guy. Way more comfortably, outgoing, happier/fun. And he was answering questions thoughtfully and talking about the team and season with good insights.
The jury may still be out depending on how the season starts and goes, but I like the new Joe. He definitely seems way more comfortable than before and doesn't sound as serious/stoic (in a mean way) to the media and others.
