There's one easy, simple solution to this problem: make EVERY bodybuilder (including Mr. Olympia winner) have to requalify for the Mr. O EVERY year. There's not much interest in the Toronto Pro right now, but don't you think it would increase if Cutler, Ronnie and other top BB's had to compete there to qualify for this year's Mr. O? If you can get the top BB's to compete in "regular" competitions, they'll sell much better.
I wouldn't pay to travel to toronto to see Darrem Charles face down Jaroslav Horvath and Art Atwood, but I would go to see Ronnie face off against Jay Cutler, Dexter Jackson, Dennis James and Chris Cormier. Granted, not all of them will compete in each contest, but pretty much every contest would have a few top competitors. Think how much more exciting the BB season would be!
