Big surprise there. Nobody wants to watch ESPN blow LBJ for 55 minutes after the main event takes place. I think minute-by-minute real time ratings of this would be hilarious. High viewership right at the start, then a huge lull for the next 45 minutes as people decide there's better stuff to watch, and then high viewership for the last 5-10 minutes as everybody flips back to it for the announcement.
Jason Whitlock on Twitter had a good point. 9PM in Cleveland would be right about the time people will be getting smashed. Not the best time for them to hear that LeBron is going to ass rape basketball in their city to death on national TV. If he leaves, I am guessing there will be a riot. Oh, and he will have to leave Ohio and never return.
