If and if else again

Ok, the problem I seem to be having is that I am unsure on how to make the program recognize if the player is in one of the "MVP" positions (C,SS,CF) before moving forward.

These three positions qualify for "MVP" status only if their OPS is above 800 for everyone else, it has to be 900 or above to be considered for "MVP". And once again, I am caught up on the "if" and "if else" statement. Again, This IS school given problem and I dont want the answer. Only insight into what I am doing wrong. I want to learn this not have it done for me. Thank you in advance.

import java.util.Scanner;

public class baseBall {

    public static void main(String[] args) {
        /* A good part of a baseball player's offensive value is captured by the    //statistic OPS - the sum of the player's on base percentage and slugging //percentage. An MVP candidate will typically have an OPS above 900, however if //they play a difficult defensive position (catcher, shortstop, or center field) //then they are an MVP candidate if their OPS is above 800. Write a program that //will prompt the user for a player's name, their on base percentage, slugging //percentage, and defensive position and report whether the player is an MVP //candidate*/


        Scanner input = new Scanner(System.in);
        System.out.println("Please enter players name: ");
        String name = input.next();
        System.out.println("Please enter On Base Percentage: ");
        double Obp = input.nextDouble();
        System.out.println("Please enter slugging Percentage: ");
        double Slg = input.nextDouble();
        System.out
                .println("Please enter position (P,C,1B,2B,3B,SS,LF,CF,RF): ");
        String ball = input.next();

        String position; 
        double Ops = Obp + Slg;

        if ( position.equalsIgnoreCase("ss")){
            if (position.equalsIgnoreCase("cf")){
                if (position.equalsIgnoreCase("c")){
                    System.out.println("MVP Candidate!");
            else
                 System.out.println("NOT an MVP Candidate!);

                }
            }
        }
    }
}
