As long as haters ridiculously blame Lebron for every single move his team's management ever makes, even when it's expressedly against his desires, we can have fun throwing it back on them.
Wait, what???
Detroit barely even had a bench in 2004. Their #1 minutes guy in the Finals off the bench was 35-year-old Elden Campbell doing 13 minutes/game.
Outside of Manu the Spurs had a shyt bench in 2007. Outside of Horry they barely had a bench in 2005. And in 1999 their rotation only went 7-deep and that 7th guy averaged 1.2ppg.
I dunno if I can say the Celtics had a strong bench in 2008. They had some average pieces, got lucky with a few guys who stepped up in key moments, but it was still a mediocre group.
The main point of a strong bench in the playoffs is to maintain flexibility against different lineups and fill in roles that aren't filled by the starting lineup. But if you have a strong starting lineup that fills all the necessary roles, and at least 1-2 strong bench pieces who can fill in at multiple positions, then you don't necessarily need a great bench.
