Where did you see an Ethier comp to DPete?
Besides batting from opposite sides of the plate, Ethier produced 4 seasons with a WAR of ~3.5, a couple more ~2.5 WAR seasons, and a career .822 OPS.
If DPete was projected to have that type of career he would be a FV 60-65 guy and would rank up there with Swanson and Albies.
