I'm a MyGM guy myself, and I was pretty pleased with the game... until the off-season. It completely ruined my outlook on the game. The trades the AI makes are worse than ever. The contracts players are signing are way too low. The AI draft logic is HORRIBLE.
Those issues completely ruin the longevity of the mode, and as someone who doesn't play online and hates MyCareer, this game holds no appeal to me until that mystical patch is released - and let's face it, that could be a long time, or it could never happen. It's really disappointing considering how good the on-court game is and how much they touted improvements in those areas.
My game is currently sitting on eBay. If that patch is ever released, I may buy it again for cheap down the road.
