Durant missed the win over the Boston Celtics on Friday night with a shoulder injury, but returned yesterday to score 32 points in a 103-91 victory over the Sixers.
"Everybody's scared because he's Kevin Durant and he scores in such a variety of ways," Brown told reporters, "He is the NBA's hottest player.
"He's always been an incredibly difficult guard. You blink and he's got a triple-double."
Durant has scored at least 30 points in each of his last 10 games.
