I'd trade Desmond and Clippard for Span. I might push them for Luke Hughes or some extra piece back, just because I want to extract a bit more for the non-Coffey package. I'd also think of offering Coffey, Desmond, and Bally (and maybe Stammen too) and see if the quantity overcomes some of the quality.
Here it stinks that Burnett is having such an awwful season. He'd be the ideal "less than Clippard, more than Coffey" veteran piece if he were performing like last year or if this was April.
