If you watched last night's game, you know why they love Pache.
He's the best fielding CF in a Phillies uniform since Garry Maddox, that catch in left CF was amazing, but then he ranges over to backup Schwarber who missed on a ball in front of him and held the runner to a single.
With his defense and speed, an OPS of .700 or so would make him a 3-4 WAR player.
Straw put up a RC+ 64 (.564 OPS) last season and was still a 1.9 WAR player
Varsho RC+ 106 (.745 OPS) for 4.7 WAR.
An OF of Crawford - Pache - Rojas would be a track meet.
