Dyson would be a nice guy to have around as a platoon bat/4th outfielder. Much better than Revere IMO.
Edit: just looked at his stats on Fangraphs now and wow. Guy has posted 1.4, 2.5, 3.0, 1.8, and 3.1 WAR since 2012. And thats with limited playing time. I thought only last season was his real breakout season, but he's been really good for the last 5 years.
