Ive heard Wheating say he wants to stay wit Vin for the time being. That may not last, but that is what he wants. Vin has also made clear on occasion that he 'works for the university of oregon, not nike'. Cook's group would have the best mix of training partners in terms of 800/1500. Cook has already coached 2 athletes to World/Olympic Medals. I personally think that would be the best option. He is a superstar in Eugene and will be just a regular guy waling down the street everywhere else in America.
Personally I would love to see him sign with someone other than Nike, or any of the Oregon stars; Centro, Hasay, AJ, Eaton, ect. It just seems so predestined that after college, they will sign with Nike, it would be cool for one to strike out on there own and say, that was the best for me in college, this is what is best for me professionally. Being the main figure in a company as opposed to one of many.
