Hindsight, that is. Doesn't mean it isn't fun and enlightening, however, as Vince Grzegorek's look at what coulda happened in Cleveland this year demonstrates:

April 2008: Andy Marte begins wearing a sign around his neck that says, "I am
not Brandon Phillips." General Manager Mark Shapiro takes note and immediately
begins looking for the franchise's third baseman of the future. What happens:
Inspired by Marte, Jamey Carroll begins wearing a sign that reads, "I am Jamey
Carroll." He receives zero more autograph requests, tells reporters he was
noticed once when he had a goatee - but only by somebody who wondered if he was
Paul Byrd's little brother.

There's much more. I'm guessing fans of just about every team could put a list like this together.
