I have nothing against Jennifer Hudson, and she is obviously a talented performer. Unfortunately, that is how her rendition came off to me i.e. just a performance.
What I found missing was all of the emotion, passion, exhilaration, and heart-break of the game and the tourney that the original version expressed so very well. I am prone to suspect this may be the difference of one performer having actually played the game of basketball vs the other never having done so.
Luther seemed to feel the words when he sung them. Jennifer was not able to do that at all. She obviously had a nearly impossible mission and that begs the question again, "why would CBS mess with something that was already done right?"
