I don't think it was from his injury, he just never tried to get his rhythm. Then when the game got down to crunch time he was just scared to test it.
Garnett kept backing off him daring him to shoot but he wouldn't. He kept forcing the drive and the help defense was great in the 4th quarter.
I hope to see the same Lebron in Game 5. If we don't get game 5 I just don't see us taking Game 7.
