What can i do to be more noticable during lacrosse tryouts?

I play defense in lacrosse, and i didn't make the team that i was planning on making. I asked my coach for another team that i play for what he thought. He said that i run and defend real well, but my passing could use more work. He also said that he thinks the coach running the tryout didnt see me or something like that. So what should i do to be more noticable during lacrosse tryouts?
