Managers do it.
Fans do it.
Even us analytical types do it, even though we should and do know better. It's sometimes hard to look at your favorite player slugging .150 in mid-April and convince yourself that you really truly believe it's just the result of a small sample size. Benjamin is a truly bad hitter, and will be again this year. His rise to the level of mediocrity at the plate last year was a fluke. I am, however, willing to wager quite a bit of coin that his OPS will rise.
