“The reason I started to play this game, the reason I fell in love with this game. Growing up wanting to be just like you, to you becoming a mentor, beyond thankful for everything you’ve done for me,” Tatum wrote.

Bryant is the fourth-leading scorer in NBA history. LeBron James passed Bryant for third place Saturday night, and Bryant tweeted following the feat.

“Continuing to move the game forward @KingJames. Much respect my brother,” Bryant said.

Many well-known names spoke to the impact Byrant had on the game. Doc Rivers was brought to tears while speaking before a game.
