People in sports are quick to forget. I remember in the 2010-11 season every single arena would boo LeBron every single time he touched the ball.
Now you hear people wowing over his plays and the season he's having. You have non Heat fans arguing in his favor about how he deserves MVP. With younger Cavs fans that grew up in the Kyrie era, I would think they would love for LeBron to come over.
Two years ago, fans were making satire videos of LeBron commercials. Now the majority of Cleveland fans are open to the idea of welcoming LeBron back.
