[Caged Great]

Smoak - .235 AVG - 9 HR - 28 RBI - .786 OPS
EE - .234 AVG - 19 HR - 56 RBI - .784 OPS

Smoak has less than half the AB's as EE and if they were the same Smoak would also have 19 HR and more than 56 RBI.

So it is possible to deal EE without losing much of anything from the roster because Smoak is doing a similar job.
