"It's a mixture of things," Davis recently told MMAjunkie.com Radio (www.mmajunkie.com/radio). "There are a lot of variables. Yes, Rousimar is a very simple person. He comes from a very simple background. He comes from a background that somebody here in the United States would have a very, very hard time understanding.
"But he does tend to go on automatic a lot, and that's something we are trying to straighten out."
I was listening to Sherdog radio and it was mentioned that Overeem might have left the US to avoid a "Out of competition drug test". I know he left the country to train in Holland again b/c his Mother is seriously ill again, so I really believe he left the US to avoid a drug test.
I'm pretty sure the only reason why he left is b/c he had to flush his system b/c if he would have taken a urinalysis on that day he knew he wouldn't pass it. Alistair sounds guilty as hell right now. He's stumbling all over the place.
