I believe what maybe started the "dive" question, may have been this weekend's "dive" by Troy Jr. in eliminations (?) But when it comes to qualifying, there are two sides of this, in my opinion. Like Pete said, many years ago, NHRA stopped inserting Pro alternates. At the time I didn't blame them. I remember one incident where a sponsored FC racer that was still in the hunt for a championship tried to buy out a qualified low buck independent racer, when he didn't qualify at the World Finals. However, that was then, this is now.
I recently sent NHRA an email when the "Winternationals" had short fields in every class except Funny Car. Jason Rupert qualified 11th, but blew up and couldn't make the 1st round. There were two good alternates available, but due to that rule, Funny Car had a 1st round bye like all of the other classes. It seemed like a real shame and I feel that with short fields being so common these days, maybe it is time to bring back the pro alternate program. This way, the fans (which pay the bills) might have a better chance to see more side-by-side-racing. Just my opinion.
