org.json.JSONException: Value at org.json.JSON.typeMismatch

I am parsing some data from a link which contains the list of premier league table. I like to use it to show in a list view. But I get JSONException and JSON.typeMismatch errors.

Below is my code:

public class ParseJSON {
public static String[] position1;
public static String[] team;
public static String[] points;
public static final String JSON_ARRAY = "data";
public static final String CHILD_ARRAY = "standings";
public static final String CHILDS_CHILD_ARRAY = "overall";
public static final String KEY_POSITION = "position";
public static final String KEY_TEAM = "team";
public static final String KEY_POINTS = "points";
private JSONArray users = null, user2=null;
private String json;
public ParseJSON(String json){
this.json = json;
}
protected void parseJSON(){
JSONObject jsonObject=null, jsonObject1=null;
try {
jsonObject = new JSONObject(json);
users = jsonObject.getJSONArray(JSON_ARRAY);
try {
jsonObject1=new JSONObject(json);
user2=jsonObject1.getJSONArray(CHILD_ARRAY);
position1 = new String[user2.length()];
team = new String[user2.length()];
for(int i=0;i<user2.length();i++){
JSONObject jo = user2.getJSONObject(i);
position1[i] = jo.getString(KEY_POSITION);
team[i] = jo.getString(KEY_TEAM);
/*points[i] = jo.getString(KEY_POINTS);*/
}
}catch (JSONException e) {
e.printStackTrace();
}
points = new String[users.length()];
} catch (JSONException e) {
e.printStackTrace();
}}}


I'm getting error message
