I think that they handled Flowers about as well as they could. IIRC, Flowers had suspect hitting the past couple of years, but he was getting great reviews from the pitchers, and his defense was quite good. The drop-off in his defense fits in with an overall theme on this team. Not sure why.
This is a tough year, but I guess that I'd prefer that they be near the bottom and clearly in a sell-off mode than in the middle of the pack. This always felt to me like a transition year or two, and it might as well happen while the red line reconstruction places an additional constraint on attending the games. But it isn't going to be much fun in August and September.
