LeBron versus Larry Bird
This is a great time to compare the two, since Larry retired after his 13th season in the league, while LeBron just finished his 13th season.
Per game averages:
LeBron
Regular Season - 27.2 point, 6.9 assists, 7.2 rebounds, 1.7 steals, 0.8 blocks, 8.3 FTA, 74.4% FT, 53.2% EFG

Playoffs - 23.8 points, 6.5 assists, 10.3 rebounds, 1.8 steals, 0.9 blocks, 6.2 FTA, 89% FT, 48.5% EFG
LeBron leads Larry in regular season Win Shares 192.5 to 145.8. He leads Larry in playoff Win Shares 41.6 to 24.8.
LeBron leads Larry in games played in the regular season, and has played 199 playoff games to Larry's 165.
After these Finals, I'd say LeBron has at least as many signature performances, especially on a big stage.
I don't think there's any question, LeBron has surpassed Larry Bird.
