excellent post! I missed the game today, but I heard about Luka from some of the dallas media. They were talking about how it looked like the same Luka/Mavericks from the times they played the Clippers in the playoffs. and I heard about his poor defense as well.
I think you hit the nail on the head about his competitiveness. He takes a lot of heat from fans for his hyper competitiveness, even in Dallas, but I want a guy that wants to win every time down the court. dirk was the same way. I remember dirk head butting a ball at a ref and asking a ref to fight him lol, and those were regular season games. he also broke things in the locker rooms and yelled at his teammates, yelled at fans on the road, yet he never had the reputation that Luka has because I think Luka is already a bigger star than Dirk was, especially early on. Of corse Dirk got to play with Steve Nash and Michael Finley early on in his career, Luka has not had that same type of help.
I think Luka will work on his fitness, and he does have a mentor in Dirk who has been open about his own flaws in his younger days and Dirk has talked about how he is trying to mentor Luka into improving his off court lifestyle as he matures. In the end it will be up to Luka to make his game better, but I agree he has done nothing but improve every year. They have won their first playoff series in 10 years. Of corse this series isn't over yet so there is no reason for people to discard Luka and the mavs yet, but worst case scenario they get swept by the Suns and no one will blame anyone on the Mavs roster because the Suns are clearly a much deeper and talented team overall.
