Plenty of baseball writers are already offering their opinions on the Diamondbacks' acquisition of Aaron Heilman, and speculating about what the pitcher's role might be in Arizona….
- Joel Sherman of the New York Post tweets that some Diamondbacks execs have viewed Heilman as a starter in the past.
- MLB.com's Steve Gilbert, however, suggests that the team plans to use Heilman out of the bullpen.
- In a separate article, Gilbert writes that he likes the deal for Arizona, as a low-risk move with upside. He notes that the two prospects the D'Backs gave up "were not exactly setting the world on fire."
- R.J. Anderson of Fangraphs leans the other way: He applauds the Cubs for getting anything for Heilman, and wonders if "giving up anything of value for a middle reliever" is smart for the Diamondbacks.
- Matthew Pouliot at NBC Sports thinks that both sides did well. He says that Heilman is a durable pitcher with upside, but that he wasn't in the Cubs' plans, and Chicago probably couldn't have gotten a better return elsewhere.
