It's hard to know what the truth is when you hear these kind of statements. Doc is not going to say too much negative to the media pregame if his past is any indicator. He will blast the team on occaision postgame, but not so much in the playoffs. This tells me we are getting a writers opinion or a partial quote.
The fact that KG is quoted as saying the team is working hard is not always a good measure of the whole team attitude IMO. He is a motivated guy and plays/practices with real intensity, but he is often oblivious to his teammates when it comes to their mental state. I think he just assumes they will follow his lead and in many cases they do, but not always.
I do not put too much weight into one game here just because Lebron had a hot nite. He is a superstar, these things can and will happen. I do not think we are 'done', nor do I think Paul Pierce is 'done' after one performance by the Cavaliers.
All of this media chatter about poor practice and bad player/team performance will disappear if when we win the next game. Then it will start again as soon as we lose another game.....predictable most of the time.
