Prancer- An example of why I feel Tara's commentating is bad:
Ksenia at worlds 2010: Tara makes a comment at the beginning of Ksenia's program that goes something like this: " I think the Russians this year are really coming strong."
That comment was just one sentence with no explanation how the russians are becoming stronger, who, when.... nothing. She didn't elaborate at all. For the average viewer who doesn't know about skating they might want a few more sentences there. She makes a lot of comments like that which tend to go nowhere.
