It's clear that Paul Pierce is less talented than Kobe.
However, the playoff matchups between the two guards has really elevated the rivalry between the two foes. First of all, the two teams are the biggest rivals in basketball and because of that, the two best players on the two teams naturally have to become rivals.
In 19 regular-season games, Kobe barely has more points per game than Pierce, leading him 26.7 to 25.2. In those 19 games, the Lakers have won 11 of them, but most of those came when the Celtics were cellar-dwellers.
What matters most is what they've done in the Finals against each other. Pierce has been heavily contained and has had plenty of assistance from guys like Ray Allen, Kevin Garnett and Rajon Rondo, especially in the 2008 Finals. In Game 3 of the 2008 Finals, Pierce scored a grand total of six points. Pierce, in the two series, has averaged a little over 17 points per game.
Kobe, on the other hand, has been difficult to control. He's averaged 27.2 points in the two series. His biggest struggles came in the first half of Game 7 of the 2010 NBA Finals. However, Ron Artest and the rest of the Lakers bailed him out that night as the Lakers won their 16th title.
It would be nice to see the two rivals meet again in an NBA Finals.
