Sorry, but way, WAY wrong ... despite their age and the circumstances involved, to say this team, and the "Big Three" especially, only care about winning "big" games, is absurd, and just not in touch with the reality of this team and what they believe in. If you've really listened closely to these guys over the last 3 years and even the last few weeks, you would know without question that they approach EVERY game with the same importance and same level of expectation.
To "let down" on any level because a game is against a team like the Nets is completely contrary to what Ubuntu is all about, and contrary to even KG's approach to life itself, let alone basketball. Have they had lackluster games? Of course. Have they had their ups and downs? Of course. They've had injuries, they've had rotational adjustments, they've had new additions to the roster to adapt to, and they've had the same personal, psychological, and emotional issues that EVERYONE has from time-to-time.
That's life, and it's NORMAL. It happens EVERY season to EVERY team, and there are NO exceptions. We are STILL one of the best teams in the NBA with a win/loss record that most teams would love to have, and we are a team with the talent and experience to be able to make the proper adjustments needed to play at their best. I'm sorry to be so strongly opinionated about this, but if you have ever really listened to these guys and understood what their about, then you would know how completely contrary this is to everything they believe in and stand for.
KG especially has made this a cornerstone of his approach to everything, and he has stated it openly throughout his entire career ... to him there ARE no "unimportant" games, and every time he goes onto the floor he goes in to WIN ... PERIOD. Ray and Paul are no different, and EVERY loss is important, every WIN much more so. The Celtics care as much about January as they do any other month of the season ... make no mistake, and when they lose, you'd better believe they feel bad about it ... just as badly as any other loss.
