realistically, I don't know how anyone on this forum could say with any certainty if he was actually good at this job or not. is minor league records the only indicator? he wasn't signing the players. do you give him credit for Montgomery or Schultz becoming great prospects? or for Cespedes or Kath falling down in the system?
the GM job is more visible, we can see what moves he's making and who he's hiring, and I'm not sure what he would've done differently to look better to fans. he seems to be doing a fine job thus far, what would David Stearns have done differently?
still, the first big test IMO is what he's able to get from Cease; nonetheless, the organizational structure already seems better than it has in years. it genuinely wouldn't surprise me if the Sox compete in the central, the team actually looks better than last season, the wildcard being the pitching staff. still, I prefer to see Fedde and Soroka than I do Flaherty or Wacha.
