I have to wonder if they just threw him in there. You'd think they let him try it out a couple of times to at least know where he should be standing and pointing.

Watching the Boom Goes the Dynamite sports anchor, I think his main problem was not being able to read the teleprompter, though his butchery of some of the NBA players names is questionable for a sports reporter. You gotta know the names.
