Championship and no poles? ever happen?

got that question: If Dale Jarrett wins the championship and ends up with no poles, has it ever happened before? Yep, five times, most recently, in 1991 when Dale Earnhardt won the Winston Cup Championship with four wins and NO poles. It also happened in 1983-Bobby Allison; 1980-Earnhardt; 1973-Benny Parsons; and 1950-Bill Rexford(The Stock Car Racing Encyclodepia)
