We gotta give nyjer a break. Everyone loved him last year and now he stinks cuz hes struggled for most of the year? We have to remember he was basically an everyday player last year. Hes got a new role this year with gomez back and the signing of aoki. It takes time to get used to changes in roles. He'll come around soon, intact he's already starting to.
As for baserunning mistakes, they shouldn't happen but they do and they happen to everyone. In nyjers case its just about being frustrated about his play.
Lets just try to remember how clutch he was last year and try to give him the benefit of the doubt at least a little while longer
