why do we even bother challegning calls
If I was Martz I wouldn't waste another timeout challenging a call. They almost never win a challenge and the system the NFL uses is stupid anyway. The referees will use any means necessary to make sure their butts are covered, whether it be not enough evidence to overturn a call, an inadvertant whistle, whatever. Stupid, stupid, stupid system. I haven't seen zebras this protected since that wild kingdom show on the serengeti (over in Africa) where they were on the refuge and lions or pochers weren't allowed. Did everyone see our good buddy, the Commish, in the stands today?
