Some Cub players have under performed based on their past accomplishments. Rizzo, Chatwood, Quintana, and Hendricks fall into that category. Others have not progressed as much as some might have hoped. Others have had health problems that have slowed them down. My view is that the under performers are likely to improve, in some cases markedly, in the second half. The inconsistency of the young players is likely to continue, but Happ, Russell, Almora, and Schwarber have all performed well overall and I doubt any of them has reached his peak. Injuries are impossible to project, but it seems likely that Bryant will come back strong, and CJ should be ready soon. No doubt, this Cub team should be in better position in the standings than it is, but somewhat underperforming in the first half is not that big a deal. They simply will need to perform closer to their talent level (and avoid bad luck) and they will win the Central, probably with ease.
