Our opinions aren't problems for the Twins or their fans, the Twins not developing pitchers is, however, a problem for the Twins and their fans. ANY ONE of us could have traded Span for a MILB pitcher. The Twins need to be judged on how well they made that trade, because anyone can follow the process of trading for prospects, but successful teams pick the RIGHT prospects.
This delta between following a process, and doing so successfully, seems to be a point of some confusion on these boards. I can follow the process for trying to hit a baseball (as could Drew Butera), doesn't mean it should be my job.
