Honestly, it makes sense he would choose the Cubs over the Red Sox. He's a midwest guy, he'd be going to a team with a very positive atmosphere going on, the expectations in year 1 will be lower. Meanwhile the Sox have a negative vibe going on, and while they are clearly more ready to win, the expectations are a WS title or bust. Also, the team he would be managing quit on it's last manager, and their fans were extremely vocal of their criticism of him when he was there last time. No brainer.
