I've always liked Mike Quade since he was the manager of the I-Cubs, and I don't think getting rid of him would help solve the problems Chicago has had. To me, it had been the players under performing. If you look at what some of our players are being payed this year and the production we're getting from them it is clearly obvious we signed a lot of bad long term deals that haven't panned out. For example, is it Mike Quade's fault that Soriano is making $19 million this year?
The Cubs were expected to have a rebuilding year, and could have over $70 million free up after this year to make some moves in the offseason. As cliche as it is to say, I'm already looking forward to next year. I think we have a future franchise player in Starlin Castro, and should try to build the team around him. To answer your question though, unless the Cubs really tank it the rest of the year (not looking good so far), I don't think he would be out after this year. I think he's given a longer leash since the team has faced big personnel changes with the manager, players, and ownership recently.
