✅ Difficulty understanding Inheritance and where to use Constructor

 abstract class Player
    {
        //base properties
        internal string Name { get; }
        internal string Position { get; }
        internal string Nationality { get; }

        //physical properties
        //all players are assigned these randomly
        public int Pace { get { return SetPhysicalProperties(60,90); } }
        public int Strength { get { return SetPhysicalProperties(60,90); } }
        
        //Methods
        static int SetPhysicalProperties(int min, int max)
        {
            var rand = new Random();
            return rand.Next(min, max);
        }

        //display Info Method
        public void DisplayInfo()
    {
        var info = new StringBuilder();
        info.AppendLine("-----Personal Details----");
        info.AppendLine($"Name: {this.Name}\tPosition: {this.Position}\t,Nationality:         {this.Nationality}");
        info.AppendLine("----Physical Attributes----");
        info.AppendLine($"Pace: {this.Pace}\tStrength: {this.Strength}\t");
        System.Console.WriteLine(info.ToString());      

internal class Defender : Player
    {
        public int Tackling { get; private set; }
        public int SlideTackle { get; private set; }
        public int Header { get; private set; }
    }
