White boys from the Midwest

Sam Caplan at Five Oz. of Pain has a post talking about Bob Arum being interviewed about MMA. In it Arum claims that the UFC is just a bunch of "white boys from the Midwest" and that "50-60%" are using banned substances. I have problems with both of those characterizations.
First off, the white boys from the Midwest point. I could care less if it was, frankly, if those were the best fighters in the world. It's simply not true, however. Though there's a good representation of Midwest white boys fighting in UFC and every MMA promotion, it's because of merit. There are some of the greatest wrestling programs in the world in the Midwest, at Iowa, Michigan, Ohio State, Iowa State, and so on and so on.
I'll use one page of the UFC fighters list as a sample. It may or may not be perfectly representative, but I don't really want to go through every page right now.
This page goes A through some of the E's:

Abbadi Danny 2-2-0 5' 11" (180 cm) 185 (84 kg)
Ultimate Fighter castmember, kind of an idiot. Sadly, niether white nor midwestern. Orlabdo FL

Alessio John 25-11-0 5' 10" (178 cm) 170 (77 kg)
Vancouver, British Columbia, Canada. Possibly midwestern, but a differnt country. Definitely white tho.

Alexander Houston 7-1-0 6' 0" (183 cm) 205 (93 kg)
Good lord! A midwesterner! Omaha NE. He also matches the male criteria, but comes up short on whiteness.

Alves Thiago 16-4-0 5' 8" (173 cm) 170 (77 kg)
Fortaleza, Fortaleza, Brazil. Brazil is noted for having a lot of non-Midwesterners roaming around, not doing Midwestern things. Same nickname as the next guy, "Pitbull".

Arlovski Andrei 12-5-0 6' 4" (193 cm) 240 (109 kg)
I didn't look it up yet, but I'm gambling he's Russian. No! The Pitbull is Belarussian. However, he is white, male, and fights out of Chicago, which is in the Midwest. I don't think that "international Sambo practitioner" is what Arum was driving at, however.

Assuncao Junior 5-2-0 5' 9" (175 cm) 155 (70 kg)
Looks male and white. From Atlanta GA, according the UFC's site. Funny note: Under strengths, lists, "heart". Damn, that's rough.

Aurelio Marcus 14-4-0 5' 10" (178 cm) 155 (70 kg)
Coconut Creek FL. Originally from Brazil. Beat Gomi in a non-title fight.

Baroni Phil 6-5-0 5' 9" (175 cm) 184 (83 kg)
Long Island NY. The New York Bad Ass is known for gassing in the late rounds, not eating deep-fried things at county fairs. Though I bet he would, especially if he could have a smoke and a beer with it.

Belcher Alan 10-3-0 6' 2" (188 cm) 205 (93 kg)
Born Arkansas (Midwest!) fights out of Biloxi MS. Damn, so close. Recently beat Sean Salmon after taking the fight on about 15 minutes notice and moving up to light heavy. Sean Salmon has no luck.

Belfort Vitor 12-5-0 6' 0" (183 cm) 205 (93 kg)
I'm guessing this fellow may be from abroad. The Phenom was born in Rio de Janeiro. I think thats in Kansas.

Berube Allen 2-1-0 5' 8" (173 cm) 155 (70 kg)
Misses the region completely. born in Maine, trains in Tampa FL. Also nicknamed "Monstah Lobstah". Should be banned forever from fighting for his acts on TUF and for his insipid nickname.

Bisping Michael 14-0-0 6' 2" (188 cm) 205 (93 kg)
Definitely white...born, sadly for Bob, in Liverpool England.

Black Jason 22-2-1 5' 8" (173 cm) 155 (70 kg)
BINGO! Born in Iowa, trains in Iowa. Midwesterner, white, male. Nailed it Bob!

Bocek Mark 4-0-0 5' 8" (173 cm) 155 (70 kg)
Toronto, Ontario, Canada. Stupid wrong country again.

Bonnar Stephan 12-4-0 6' 4" (193 cm) 205 (93 kg)
Munster, IN , USA...that is pretty Midwestern.

Braga Wander 16-0-0 5' 8" (173 cm) 155 (70 kg)

The SLC, UT

Byrnes Steve 6-1-0 6' 0" (183 cm) 185 (84 kg)
Born in Cleveland! fights out of Hawaii though, noted for its lack of whiteys not wearing tourist gear.

Carneiro Roan 11-5-0 5' 9" (175 cm) 170 (77 kg)
Rio De Janeiro, Brazil

Carter Shonie 66-14-7 5' 9" (175 cm) 170 (77 kg)
Chicago IL. Deceidely not white tho. The blinged pimp goblet gave that away.

Caudillo Luke 15-7-0 5' 7" (170 cm) 155 (70 kg)
North Platte, NE. Midwestern also. Lacking in whiteness. Bob's theory is looking not only stupid, but pathetic so far. What do you say to fighters who work hard, and prefect techinque, and show all this heart and effort, and get dismissed by some corrupt old scumbag like Bob Arum? Who's white, I'm afraid to say.

Chalangov Ansar 7-2-0 5' 11" (180 cm) 170 (77 kg)
2-3 isn't bad I guess. It just says "Russia" on his profile page.

Christison Dan 8-5-0 6' 8" (203 cm) 265 (120 kg)

OK, thats 51 fighters. Decent number. Let's see what the numbers show.
8 are white and listed as being born in the Midwest, or fighting out of it if no birthplace was listed. Two of those are born in the midwest but fight elsewhere. so I'll be generous and say 8. that's 15.68% of the sample that is "White boys from the Midwest". Given that aproximately 65 million people live in what's generally defined as the Midwest, that is a good percentage, since something like 6 billion people live in the rest of the world. Unfortunately, it puts a definitive lie to Arum's claims that they're all the UFC has to offer.

He also claims "50-60%" of fighters test positive for banned substances. Though I don't have the resources to do this quickly, I pretty strongly feel this is incorrect on its face. I recall several high-profile cases of people showing up positive, obviously Stephen Bonnar, Sean Sherk and Hermes Franca. I can't think of too many others, though I'm positive they've happened. Sherdog shows the UFC as having put on 11 events this year, with six more to come so far. That's 90 fights this year. From what I know, 2 fighters have tested positive in the UFC. One event from what I can gather was not tested, that's the UFC event in London, "Nations Collide". So take those 10 out. 80 fights, 2 positives, one under appeal. Look, I'm no statistician, but I can pretty plainly see that is not "50-60%".
So none of Bob Arum's points are true. He's a senile moron who should not be given any credibility at all.
Good night Bob.
