Yes, well despite my efforts to push them to expand the online capabilities. I think its just slightly outside of the capabilities of the programming team right now. Which is fine. Hopefully enough OOTP13's sell that they can hire someone who can focus on online play!
That being said, a buddy and myself a few years ago used to trade league files back and forth. We would take turns playing a series at a time. So you'd manage a series, then the next one your AI takes over. With the use of 7-day line-ups, and tendencies, you get a pretty good control over everything.
Also you can set it up so that you can watch the replays before seeing the ending when you get the file back. So you can "watch" the series unfold" but without control over the results.
Worked for us until we moved on to a busier lifestyle.
