Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###

### Question ###
When Herb Graver played, how many field goals were made when there were more than 50 points, less than 15 touchdowns, and more than 0 extra points?
