I can only guess Stubbs is dealing with some mental issues, both at the plate and in the field. Now this is only guessing, but he seems to be the kind of guy that beats him self up mentally. He needs to go to the Brandon Phillips school of playing mentality. Phillips can make the biggest bonehead play and then turn around and make the defensive play of the year. Things just don't get to him. On the other hand Stubbs seems to be affected for a long time by his mistakes and it just keeps on building up.
