Actually, Robertson did ask for a lot of money, but Chicago do not have money anymore because they spent it all to bring Farah and Rupp to Chicago. Look to the field, it is going to be a lot of American 2:12 marathoners, Rupp and Farah. It is pretty much a show off between Rupp and Farah. I know for fact they did not accept someone who has 2:07 because they did not want him to beat Farah or Rupp. The guy is in a great shape and he has been improving his marathon PR's. He wanted to run Chicago because he want to run 2:04-2:05 but, Chicago will not accept him.
