I realize the question is potential, but it's hard to get away from present day comparison. And in truth, the underlying interest here (the 'elephant in the room') remains how badly DA erred in trading Perk. And Stiemsma has some relevance in the conversation even though he was not part of the trade. If DA is able to effectively replace a traded part, a bad trade becomes more palatable.
I would trade Stiemer for Perk in a minute. But, if JG were healthy, I do not think I'd trade GS/JG for Perk. Also, thinking big picture, DA has replaced Perk, BBD and JG with Bass, Stiemer, and Pietrus. And he still has JG possibly returning and the Clipper pick. All in all, and in large part due to Greg's emergence, I am not missing Perk very much right now.
