(Matthew Emmons-USA TODAY Sports) Cowboys infected with too much optimism? Jerry Jones: We're a glass half-full team JON MACHOTA | Published: Tuesday, September 24, 2013, 5:43pm Jerry Jones showed Tuesday another example of how far his optimism can reach. During the first few minutes of a local radio interview, the Dallas Cowboys owner and general manger seemed to be having a great morning. Then he dropped the news that Pro Bowl defensive end Anthony Spencer is probably facing season-ending knee surgery. But then Jones went right back to talking about how well defensive coaches Monte Kiffin and Rod Marinelli have utilized their talent upfront. He sounded nothing like an owner who recently learned he's likely about to be without one of his top 10 players for the remainder of the season. Former Cowboys coach Jimmy Johnson said Sunday that the Cowboys have a disease called "optimistic infection." Johnson made the case that the Cowboys think too highly of themselves after wins and the result is usually getting back to reality and suffering a loss the following week.
