At 34 years old, when players have a breakout year, they seldom ever, in the history of baseball, ever replicate them, unless they were "enhanced". Pretty sure Scutaro doesn't do PED's. Therefore, the likelihood of him being a top ten BB guy or hitting 20 points higher than his career average or hitting 70% more HRs than his previous high in HRs or stealing 100% more bases than he had ever stolen in one year before is extremely small, IMHO.
Also, unless you are a catcher, I don't see what playing different positions in the field has to do with effecting what you do at bat.
Lastly, I stand by my "pathetic" prediction because those numbers are a helluva lot closer, percentage wise, to his career averages than last years numbers were.
