Steroids? I assume you can back that statement up and that it isn't just same baseless ignorant rant. I can name two MMA fighters off the top of my head that have tested positive and thats Bonnar and Sylvia. I can also name two boxers Vargas and Toney. So it would seem steroids are a small issue in both sports.

In regards to boxers seemless transition: both Mercer and Botha were unsuccessful in their K1 ventures. Jeremy Williams has had some success against questionable competition in MMA so we will just have to see.
