Span is a very good CF and leadoff man who is on a pretty team friendly contract. Revere is a slap hitting, noodle arm (albeit great range) who projects to be a PR and a 4th OF. The difference between Span and Revere is quite Large. Span's one real "weakness" is getting picked off to much, Revere's weaknesses include: zero arm, zero power, zero ability to draw a walk (because of his zero power) And I actually am one of the Revere supporters here, but its just reality. Amen to all about Span. He is one of the most productive players on the team--OK a bad team, but still Span would represent an improvement over most CFs--especially on a cost-adjusted basis. Ergo, money that didn't have to be spent to get those 4 Wins can be applied to upgrade at another position to improve the WAR rating there.
