No, I'm evaluating role. Chavez provides value as a SP, not a RP. So yes, there's still time for him to start games this season (injuries, innings limits, spot starts, etc), but as a RP, he does not provide enough value to justify losing 3 years of control and adding $4m in salary.
Not a big deal. The trade was made for depth, and it turns out Sanchez became a viable option, and even Floyd became one as well, so the deal was done for logical reasons.
