It would be great to see them fix the simming stats issues in the patch but realistically I expect them to wait for NHL12 and possibly with a similar strategy to FIFA's whereby they went for a complete overhaul of the engine behind their franchise mode.
I simmed through 5 seasons to give it a test drive and I felt as if it was completely random. I know the NHL can be unpredictable from one year to the next so I don't worry about it too much but on my sim both Chicago and Detroit missed the playoffs for the first two years, Washington only had one season where they comfortably made the play-offs while the Islanders took 3 out of the 5 Stanley Cup's on offer.
As for player stats during the season, they just felt way off.
