I don't want to start pointing fingers here. For one, I'm pretty sure that Jim Mora informing his anchor that he's completely full of shit through a third party was the most entertaining part of that post-game coverage. Also, that one obscenity wasn't anywhere near as appalling as the performance of the team being covered by the person who accidentally used it. However, if we are going to start distributing blame then the two people sitting next to an 82 year old man with his head - almost literally - in the clouds are going to have to bear the brunt of a relatively harmless, live expletive.
I don't know if there is some "on-air" tell that was missed, but something tells me that Jim Mora officially stops taking hints at 9:45PM. That's why his co-panelists should have been more wary of their co-worker's level of disengagement before casually asking him a question in a conversational tone. Considering the fact that Fletcher Mackel was reacting to the "shit" before it even made it to the airwaves, I am pretty sure Jim Mora responds to 95% of statements with which he disagrees by telling the source of them that they are full of feces. That's why it's on Fletcher Mackel to make sure that the senior citizen seated next to him doesn't get caught off guard once the cameras start rolling. I don't know what age it becomes socially acceptable to mentally check out while on the clock, but you can bet your sweet ass that it's under 82.
