I was once building a team for a left power park, and planned on Josh Gibson and Kiner being the RH offsets to a team of left bombers.
Draft was a disaster, got Gibson, no Kiner, and none of my LH homer hitters.
I need to start from scratch, so offer Gibson to a guy in a RH homer park for Maris.
Seems lopsided against me, I thought, but Maris was something to build around, and removing Gibson freed up a lot of salary for a rebuild of the roster.
