I agree Span plays great D in CF but he hasn't posted a postive UZR for us since 2013. Either way there both great players but I think Taylor will be the one roaming CF for 2016+
Those of us who think Span is better defensively would probably all agree that we would lose little by replacing him with Taylor. Defensively, that is. Offensively, Taylor doesn't come close to compensating for a loss of Span. And losing Span leaves a big hole at leadoff. Taylor certainly is not a leadoff batter.
