When Pau Gasol joined the Los Angeles Lakers just over 15 years ago, the Spanish 7-footer banished his ego, redoubled his work ethic and immediately turned a struggling team into contenders who eventually became champions. Gasol and Kobe Bryant did it all together, and their numbers now hang side by side in the Lakers' arena. The Lakers retired Gasol's No. 16 jersey Tuesday night, honoring the genteel big man who spent the best seasons of his 18-year NBA career with Bryant in Los Angeles.
