44. Matt Belisle (Rockies career WAR 5.6)
Like the last player on this list, Matt Belisle is a high-round disappointment that had his best years in purple pinstripes. He didn’t always have the lowest ERA, but was above average to All-Star level every year but two while rocking the purple.
He never pitched in less than 66 games in a full season as a Rockie. He led the league with an unreal 80 games pitched in 2012.
