I can't imagine many extensions coming any time soon. When looking at the direction Ricketts is tanking the franchise, why would anyone want to stay here long term? Plenty of owners that are trying to win, not just profit.
Seriously, the Cubs haven't even finished as high as 2nd place (!) since Jed took over. Drowning in a sea of mediocrity, and salary dumping as a large market (Schwarbs, Darvish, Belli) is just sad.
