If you want to know why the Dallas Mavericks are down 0-2 in the first round of the playoffs, look at the boxscores of this year's Mavs-OKC playoff series so far vs. last year. Then look for owner Mark Cuban. Last year, nine Mavs contributed. This year, you have six. Vince Carter has been a liability, only hitting seven of 23 shots. Brendan Haywood has proven he is a backup center, only averaging three points and 3.
