Defensive Strategies to limit elite player

Hey everyone. I'm coaching a high school team this year and I'm in charge of the defense. We have a game coming up against an opponent with arguably the best player in the state. I don't see much threat on their team beyond this player and if we can limit him in the game, I'm confident our defense can hang with the rest of their personnel.

My question is...aside from locking him off, have you guys deployed any other strategies to limit game changing players on the opposing team?

We do have a lock off set in place, but I'm interested to hear if y'all have any other ideas/strategies.

Thanks in advance!
