I just want to state this plainly. The quote above is you playing the victim and being a HUGE *******. You have been provided links, you have been provided explanations. When you either failed (or refused) to understand them, you lashed out at everyone LIKE A BIG JERK. Here's another article you can read. http://www.fangraphs.com/blogs/granderson-and-left-field/
The CF-playing-a-corner guy doesn’t magically lose some range when shifting to a corner. His physical abilities are the same, and his ability to cover ground to his left and right remains the same. The only difference is that instead of covering two gaps, he’s now covering one gap and one line. (...) The total difference in defensive performance between the two alignments is simply the drop in value in right-center balls caught minus the rise in value in left field line balls caught. We’re talking about a marginal difference on just a handful of balls in play over a full season. We’re talking about fractions of a run.
