<p>If I am a captain of three athletic teams, is it good?</p>
<p>It is OK. Are you continuing these sports in college or have you been doing these sports for a while? Do you have awards/accomplishments in them? There are many instances of teams making all the seniors "captains" of the teams so they can put it on their college resumes so it has been rather diluted a bit. But generally it is good.</p>
