We have played 9 different starting OFs this year. I can only imagine the number of combinations of OFs we have started, and then multiply it by all of the different IFs they have played with too.
Again for the record, the OF we started in the finale in Pittsburgh was our 7th, 8th, and 9th OFs on the pre-season depth chart, two of which weren't even on the roster in the pre-season.
