I guess it depends on what you mean by poorly. 2012 will be a grace period where almost any result would be accepted by Ricketts. But if they aren't winning 85 games by 2014, I'm guessing the new guy will start to have pressure. If they go out and win 81 games every year, that would be a poor job, but he'd probably keep it for a long time. The GM's going to be judged more on the decisions they make in the short to medium term versus wins and losses. The manager will get the heat unless the new GM makes a bunch of dumb moves. Obviously if the team is sub-.500 for several years the GM would get canned but that doesn't seem likely with the amount of $$$ the Cubs have to play with.
