I simmed as far as the game would let me and have been poking around at things.
*One thing I did notice was that Defensive players had some whack PD%:

*One confusing bit regarding the UI is during Staff Hire phase. When I don't need to hire a coach the correct thing to do is sim one day forward. Also, after you hire a coach you still need to hit the sim one day button. The game doesn't tell you this, however. Perhaps this info should be added to the bottom of the screen (where it's already telling you whether you must hire someone or not) or a button to "Skip" up near the "Hire X Coordinator" button. I'm sure the Manual mentions something about this, but I can't access it atm since Solecismic.com is currently down.
