But remember when Span was signed. He was coming off two years of .800 OPS and nearly a .400 OBP. He regressed, just as speed guys often do in time as the league adjusts. But even after Span regressed, he was still a valuable player. Can you really say that for Revere? That's the difference between the two players. Span regressed from a .320/.390/.410 guy into a .280/.350/.370 guy. That still has a lot of value in an up-the-middle position. Even as Span's BABIP normalized, his walk rate and power remained (mostly) steady and after a few years, was still considered an above average centerfielder. If Revere's BABIP drops, he's screwed. He's instantly a fourth outfielder. Outside of mentioning that they play the same position, we should stop comparing the two players. Span is the superior player in almost every way. As for Revere's future, there isn't a lot to project there. He's never taken a walk in his career. Learning to do so now is pretty far-fetched. He puts the ball on the ground far too often to be a power threat. He's still young and could develop a little more strength but it won't be significant and given his ground ball rate, could just mean that he starts hitting groundball outs to fielders a little faster than he did before (at the same time his speed is declining). There's just nothing in his skill set that projects to being a quality player over the longterm.
