My bold prediction is that the Cubs finish a few games over .500, Nico cements himself as the best hitter on the team.
Not bold, but this team is built to be mediocre while they wait and see what percolates on the farm.
I suppose a bold prediction would be that they are a lot worse or better than mediocre. I don't think Happ is going to be as good as last year, but Bellinger will be better. Swanson is going to have a difficult start to the year, but at the end, he'll be right around his career norms, maybe +6 HRs.
