Do you still need help with this? I would be glad to help. Because you have the same teams, divisions etc as real life, my first thought would be to take a look at the real life schedule- how many games are played against each division opponent? How many times do you play against non-division same league opponents? How many interleague games per team, and against how many unique opponents?
But without even looking at the real life schedule, you need to establish your goals first. For example, minimum of 2 division matchups vs each division opponent. How random would you like the schedule to be (does it matter)? Let me know of all of your requirements if you're still looking to schedule it up.
Also if you could help with mine I'd greatly appreciate it. Dynasty commish in my first year for the dynasty: viewtopic.php?t=456762
