A football team is just a list of football players. Therefore, I should

Answer 1

class FootballTeam : List 
{ 
    public string TeamName; 
    public int RunningTotal;
}

Anyway, this code (from m-y's answer)

public class FootballTeam
{
    // A team's name
    public string TeamName; 

    // Football team rosters are generally 53 total players.
    private readonly List _roster = new List(53);

    public IList Roster
    {
        get { return _roster; }
    }

    public int PlayerCount
    {
        get { return _roster.Count(); }
    }

    // Any additional members you want to expose/wrap.
}

Means: this is a football team which has management, players, admins, etc. Something like:

This is how is your logic presented in pictures…
