With that said, Williams will never be considered the top player in the world again. In fact, there's a good chance she will never win another Grand Slam.
She had a solid 2010, but 2011 was so riddled with injuries that it's tough to be optimistic. Williams can play well for short bursts, but she simply can't sustain it.
Williams is one of the greatest female athletes of all time, but her career is nearly over.
As for her reign at the top? It's long gone and it'll never happen again.
