Doc Rivers discussed the Philadelphia 76ers' game plan to guard Trae Young, saying that the refs need to allow Ben Simmons to play "physical, good defense."

The Sixers are currently down 1-0 in the series. 

"We like Ben on Trae," said Rivers on Monday. "Trae, he does a great job of drawing fouls. So, we got to be careful with that. Some, he gets fouled. Some, Trae sells them pretty well. So, listen, if Ben is allowed to guard him, then, yeah, I'm all for it."

Young had 35 points and 10 assists in Game 1. 

Rivers said that Simmons, who had four fouls in Game 1, needs to be allowed to play aggressive defense by the refs.

"Aggression shouldn't be a foul," Rivers said. "One of the things I've done, I've catalogued those plays all year. So it's not just Trae. In general, how many times Ben has been called for fouls for playing just physical, good defense. Arms are in, he's physical, he's doing nothing [against the rules]. The offense is bumping just as much as the defense."

Danny Green was the primary defender on Young in the first half. The Sixers found more success in the second half, holding Young to 10 points on 3-of-10 shooting from the field.
