When the Los Angeles Lakers and Boston Celtics both ended up down 3-0 and facing a sweep, I opined that the Lakers would win Game 4 and Boston would get swept.
For one, the Lakers were playing on their homecourt. Also, they had LeBron James. Much to my own demise, I often give too much credence to the great one. When the Spurs led 3-1 against the Heat in 2014, James stated that he plays best with his “back against the wall.” Of course, the Heat lost game four proving otherwise.
James, the generational talent that he is, tends to view himself as an underdog which, I believe, is what keeps him under Michael Jordan in the argument for GOAT (although I agree with Sledgehammer5050 that the GOAT is Kareem Abdul-Jabbar, but that is for another day).
