It isn't just a "Kerr problem." This extends to the whole concept of the new league.
We already had a fabulous league that hosted meaningful one-day meets. It was called the Diamond League. The problem was that there were 13 or 14 meets each year and most of those have no "meaning" to the broader track fans. I don't really care about some random early season meet in China or North Africa. Sorry.
We could have solved this problem by designating four of the existing meets as the "Classics" and building them up. Brussels, Paris, London, Pre. Something like that. Make the pay-out $100,000 dollars to the athlete that wins all four of those meets and now you have a series similar to the Grand Slam in tennis.
Just making a new league is doomed to fail because the meets have no history (they are not classics) and nobody wants to watch a three day meet where you get paid only if you win in your off event as well...
