Answer: Kobe Bryant and Shaquille O'Neal
Although they were Laker teammates from 1996-2004, Kobe and Shaq never appeared to get along the best. In 1996, Kobe had just graduated from high school and had been traded to the Lakers from the Hornets; he was young, confident, and very out-going, boasting that he would lead the Lakers in scoring. Shaq, on the other hand, had just been signed as a free agent; his view on the situation was "I'm not gonna be babysitting." Obviously Kobe needed some time to mature as a player, but Shaq was looking for a championship ring. Even though that eventually happened (three times, in fact!) the two continued their feuding. At the end of the 2003-04 season, Shaq chose to be traded to the Miami Heat, while Kobe, now a free agent, resigned with the Lakers. After the announcement was made regarding the Christmas Day game schedule, a few comments were traded back and forth. On the day of the game, however, the two players bumped forearms and played. This game became the most-watched Christmas Day game ever, with 13.2 million viewers.
