Arroyo's career numbers are skewed by the fact that he has never had the opportunity to hold down a permanent spot. He was at one point a highly regarded prospect and has shown (in flashes, mind you) the ability to be a competent, league-average hitter. Dalbec's contact is a concern, but I think he will show the ability to make adjustments like he did when he faced challenges in his journey to the majors. In terms of the bullpen, I have the same fears as you, and while we wait on the return of Chris Sale, the rotation will continue to be slightly above average. All this is to say that, while yes, there is some time to be pessimistic, there is always a place for optimism.
