Use data-binding, best feature Windows Forms come up with ;)

var list = new[]
{
    new Team { Id = 1, Name = "One" },
    new Team { Id = 2, Name = "Two" },
    new Team { Id = 3, Name = "Three" }
};

combobox.ValueMember = "Id"; // Name of property to represent a Value
combobox.DisplayMember = "Name"; // Name of property to represent displayed text.

combobox.DataSource = list; // Bind all items to the control

Selections can be accessed by Selected.. properties of combobox.

var selectedTeamId = (int)combobox.SelectedValue;
var selectedTeamName = combobox.SelectedText;

var selectedTeam = (Team)combobox.SelectedItem;

Notice that SelectedValue and SelectedItem return object type, so you need cast it to correct type before using.
