Sweepstake Generator

Highly topical now the world cup is on! Here is my sweepstake generator class

class SweepstakeGenerator
{
  public class PlayerTeamPair
  {
    public string Player { get; set; }
    public string Team { get; set; }
    public override string ToString()
    {
      return (string.IsNullOrEmpty(Team) || string.IsNullOrEmpty(Player)) ? 
        "" : Team + " - " + Player;
    }
  }

  public static IEnumerable AssignTeams(
    IEnumerable orderedTeams, 
    IEnumerable namesArray)
  {
    Debug.Assert(namesArray.Count() > 0, "No names in the names array!");
    List names = new List();
    List teams = new List(orderedTeams);
    List assignedTeams = new List(teams.Count);
    Random random = new Random();
    int teamIx = 0;
    while (teamIx < teams.Count)
    {
      if (names.Count == 0)
      {
        names = names = new List(namesArray);
      }
      int nameIx = random.Next(0, names.Count);
      assignedTeams.Add(new PlayerTeamPair() { 
        Team = teams[teamIx], 
        Player = names[nameIx] });
      //Debug.WriteLine(teams[teamIx] + " - " + names[nameIx]);
      //Console.WriteLine(teams[teamIx] + " - " + names[nameIx]);
      names.RemoveAt(nameIx);
      teamIx++;
    }
    return assignedTeams;
  }
}

and sample usage

string[] teamsOrderedByBettingOdds = new string[] { 
 "Spain", "Brazil", "Argentina", "England",
 "Holland", "Germany", "Italy", "France",
 "Portugal", "Ivory Coast", "Serbia", "Mexico",
 "Chile", "USA", "Paraguay", "Uruguay",
 "Cameroon", "South Africa", "Ghana", "Australia",
 "Denmark", "Nigeria", "Greece", "South Korea",
 "Switzerland", "Slovakia", "Slovenia", "Japan",
 "Algeria", "Honduras", "North Korea", "New Zealand"
 };
string[] teamsOrderedByGrouping = new string[] { 
 "France", "Mexico", "South Africa", "Uruguay",
 "Argentina", "Greece", "Nigeria", "South Korea",
 "Algeria", "England", "Slovenia", "USA",
 "Australia", "Germany", "Ghana", "Serbia",
 "Cameroon", "Denmark", "Japan", "Netherlands",
 "Italy", "New Zealand", "Paraguay", "Slovakia",
 "Brazil", "Ivory Coast", "North Korea", "Portugal",
 "Chile", "Honduras", "Spain", "Switzerland"
 };
string[] teamsOrderedTop8AndThenByGrouping = new string[] { 
 "France", "Argentina", "England", "Germany",

string[] namesArray = new string[] { 
  "Bob", "Ron", "Tony", "Jim", "George", "Ben", "Alf", "Dirk" };

IEnumerable playerTeamIter = 
  SweepstakeGenerator.AssignTeams(
    teamsOrderedTop8AndThenByGrouping, namesArray);
foreach (SweepstakeGenerator.PlayerTeamPair playerTeam in playerTeamIter)
{
 Debug.WriteLine(playerTeam.ToString());
}
