What's the problem with the USOC the tri qualifies at world cup events and even the world champs?
Different issues.
Each NGB establishes its own specific rules for team selection. The USOC must approve them and those selection procedures must follow some guidelines and issues related to the Ted Stevens Sports Act.
For instance, USATF could state that the top 3 people with the fastest times in the world between date X and date Y qualify for the team and hold no trials.
When it comes to sponsorship, in order to use the phrase "Olympic Trials" the organizer must follow very strict guidelines in everything from sponsorship to uniform rules. For instance, if the "OT" term is used, Pepsi or Gatorade cannot be sponsors (Coke and Powerade are USOC sponsors). In some ways use of "OT" limits the promoter. PLus the USOC gets into more micromanaging--and that can be a pain in the ass.
