LN plays knowing that skill wise they know they are some of the best out there. What they don't do is play like they have to play that darn good against every team, just like you would see a team overlooking an opponent and getting trapped and beat like Alabama did against Oklahoma.
LN knows how good Kearney is. So they are going to play their best like they did against BO, Cardinal Ritter, and Phoenix Central out of Alabama. When it comes to their emotions and self discipline, these kids are going to play like children. Kearney will play rough and so will LN. Will there be any fights, maybe. It is hard to keep those inner city kids in check and I don't envy those coaches jobs to do that. Shoot, some of those coaches, family, and fans are just as bad.
Plan on it happening, I would be surprised if they come in with their emotions in check.
