Have your team sit together again during the JV game or whatever contest precedes yours. First of all, it looks good, and your players should want to look good. Whether they're wearing travel warm-ups or dress clothes, by sitting together and wearing the same things, they put off a posture of success. The opposition sees that, the fans see that, and the other coaches there, the opposing coaches and those who are scouting, will know that you and your team mean business.
