None, I repeat none of the players that Walt has traded away have went on to be stars. Wood has the best chance, but he would have been the 6th or 7th starter here. Alonso could not play a very good LF, and Grandal was blocked, but that turned out to be the least of his problems.
The organizational shift to pitching and defense, has more to do with lack the lack of top hitting prospects, and the last two drafts of all bat Winker, and Ervin have shown the Reds are working to improve that.
I am interested to see how Walt works this offseason being on the same page as his manager for the first time since he has been here.
