I've seen this happen before. Does anyone know why this happens? more importantly I sent a ticket in hopes that I get a response before my game tonight. but it's a Sunday so fingers crossed.
 Anyone else exp this and how to properly game plan both teams, including depth chart.  I feel i have a better team but game 1 is a SimAI with all upperclassman almost Sr'd out. game 2 against a good human with lots of experience. He has a younger team but could easily out coach me. I would like to game plan both games.
Thanks in advance

I don't think there's a good solution for you at this juncture. If you'd noticed it sooner, maybe they could've moved the SIM game to the open slot.  I'd game plan for the human coach and take my chances with SIM

why it happens is because there are not an even number of teams such that there is exactly 10 games for each team. Why they don't have the simai play each other in these cases seems like lazy programming, to me, but I know nothing about programming...

you've done basically what you can at this point - I try to remember to check my schedules whenever a new season starts just in case this pops up...I've never had it happen to me yet though... and if all else fails, I'd probably go with kypride's advice.
