TV tonight

Anybody check out Brock Lesnar on E:60 tonight? I was glad they showed some highlights and gave him some background credibility. This dude was a stud in JUCO and D1 national champ in collegiate wrestling.
Too bad he didn't transition into MMA earlier, sounds like he went through some drinking/pain med issues. Thankfully he recognized the behavior and didn'tcontinue the downward slide.
When the interviewer hinted at Brock's size, he abruptly ended the interview. Good for him, theguy is huge, but he's beeen a freak since college. When they asked Dana White, his responsee was something along the lines of-Anybody would be STUPID to use steroids in this sport. This is due to the amout of testing these guys endure.
Anyway, seems as if everyone on the UFC 91 come back clean on their preliminary drug test...
What are your thoughts on steroids in MMA? Do you think professional sports are stringent enough in their testing? Let me know!
