Oh come on Gil, you're better than this. That's a goddamn, outright lie.
Lebron has taken 136 game-winning/game-tying shots in his career, and they're spread over the whole career. There is only ONE season where he took fewer than 6, and he's had as many as 15 in 2007, 17 in 2008, and 15 in 2013.
I didn't think I'd have to post this again so soon, but you appear intent on acting like it doesn't exist:
2004, attempts first game-winner in just
5th NBA game, makes first game-winner by getting a steal and layup with 16 sec left against the Nets to cap off a 41-6-13 game...at the age of 19.
2005, hits his first game-tying three, right over prime Artest with just 1.7 sec left in regulation in the season opener (can't find video).
Pacers vs. Cavaliers - Game Recap - November 4, 2004 - ESPN
2006, the first player in history to hit multiple game-winners in his very first series right out of the gate.
2007, scores 29 of the last 30 points in overtime in the decisive ECF game, including the game-tying shot in regulation and the game-winning shot in overtime.
2008, hits 7 game-tying or game-winning shots and duels Paul Pierce to the end of Game 7, scoring 45 against a stacked title team with almost no support.
2009, hits that huge fadeaway three to win Game 2 of the ECF against Orlando, and was an inch from nailing back-to-back threes to take Game 4 as well.
2010, one of his better years with four game-winning/game-tying shots, but none of them were particularly special so I'll throw up his buzzer-beater from 2009 instead:
2011, dominates every 4th quarter against Chicago in the playoffs, including the elimination game where he scored the final 10 points while holding Rose to 1-10 shooting to come back and win.
2012, the title run (with both Bosh and Wade hurting) goes without saying, especially Game 6 against Boston
2013, an even more impressive title run, especially the huge shots in Game 1 against Indiana, and Game 6 and Game 7 against San Antonio.
2014, drains that classic buzzer-beater three against the Warriors.
2015, when he not only called his own number to make that enormous game-winner in the ECSF against the Bulls, but took pretty much EVERY damn shot against the Warriors in the Finals while his entire team was in the ER.
2016, scores 9 of the final 12 points in Game 7 of the NBA Finals and had the clutchest block in NBA history to cap off the greatest 3-game stretch in Finals history
2017, hit big threes against the Bucks and the Wizards to win games.
I mean, you're right, other than hitting 42 game-tying or game-winning shots over the course of his career (including 8 in the playoffs > Kobe's 7), and having the best clutch time stats in the NBA nearly every year, he's certainly tried to keep those situations to an absolute minimum.
