I want to start doing more open thread chats. Today's is a thought exercise in predicting the future. What does 15-year major leaguer David Ortiz--who is now hitting .324/.390/.602 with 14 homers in his age-35 season--have to do to be worthy of enshrinement in Cooperstown, whenever he decides to hang it up? Is he already worthy? Will he never deserve the right?
