>> you can imagine what she's going through, not just the physical pain , but the psychological impact of having a knee that may at some point at 75 miles an hour give out on you. very vonn says she and woods have talked about how champions play through pain. he himself last tasted glory when he won the 2008 u.s. open on a broken leg , something reported afterwards saying you may have just seen the best of me. though vonn has made progress on her march towards sochi , her own stubborn confidence has been shaken.
