It's not like the guy has never delivered. Saying he's only ever talked a good game is pretty unfair. The guy even says that in so many words, but can't resist leaving that impression anyway.
He buggered his knee on purpose? I mean it sucks, as it does with any number of players who are often injured. But I don't think that lends him to being judged for any moral failings.
I have enjoyed the talk about defense, and not looking for numbers other than wins. I don't see how having that kind of focus rings hollow. It's not like he said he was going to come in and carry the team on his own back, which would sound stupid, unwelcome and probably ring hollow as well.
If I was SJ I might even email him.
