Players and their stats is like picking a stock in the market. You may see terrific prior performance of that stock but nothing is guaranteed from past performances, there are other factors involved that sway numbers.
And that is what some people see with regards to Peraza and Volpe.
Volpe probably has the better mental makeup than Peraza. His(Peraza)minor glove at SS may not be the same in the majors because his mental makeup may affect him. Both players obviously had slumps in the minors with the bat. Did it affect their defense? How is a batting slump in the majors going to affect them? What about the NY media? How will they react during tough questions? Do we know how they are when they first come to the Stadium prior to a game? How is their mood? Are they affected by outside issues? Do issues outside that nobody knows about affect their play? From what I hear Volpe has what it takes to play in NY. I’m not saying Peraza doesn’t but why do they put Volpe in the golden child category? A flashy glove at SS and a terrific range doesn’t cut it. There are more factors involved that we don’t know about with Volpe and Peraza.
Sure the perfect world suggests Peraza at SS and Volpe at 2nd or 3rd. But a perfect world doesn’t exists.
