Number 5: Corey Dickerson (4.4 bWAR, 4.1 fWAR, three seasons as a Rockie)
He only played three seasons with the Rockies and he only played more than 70 games in one of those seasons. However, when he did play, he played very well. He hit .299/.345/.534 with an OPS+ of 125. His WAR gets knocked down, however, by his defensive numbers.
He became a Gold Glover with the Pirates in 2018 and the numbers show that he has been an average to above-average outfielder elsewhere but he had -12 DRS in 265 games as a Rockie.
The Rockies traded him to Tampa for German Marquez and Jake McGee so, particularly for Marquez, that ended up being an excellent trade for the Rockies. Nearly two years ago, Rox Pile’s David Sharp reflected back on the trade.
