Given the unreliability of all the trade rumor sites and "journalists", I think the best off-season move is to read Jim Brosnan's, "The Long Season". Before Bouton wrote "Ball Four", Brosnan kept an account of rthe 1960 season. Might hunt down the book about Mickey Vernon, the long-time Nats 1B who won the AL batting title twice. I went to my first game, age six, to see Vernon receive the Silver Bat from Hillerich and Bradsby.
Meanwhile, I have no idea what Rizzo will do. I hope he ignores Robbie Cano, as much as I admire Cano and as little as Rizzo cares what I, or any other fan, hopes.
