LAS VEGAS -- Roy Nelson isn't afraid to say what's on his mind even if he's risking a beatdown somewhere down the line.

Speaking to the gathered media at the UFC 143 workout day, "Big Country" is a big backer of Junior dos Santos and had nothing but nice things to say about Fabricio Werdum, his opponent on Saturday night. When it comes to the recently retired Brock Lesnar and Alistair Overeem, he's not too impressed.

"Other people have the easier roads [to a title] shot, like Overeem. He beat Brock ... ooh. Now you get a title shot. Whatever," joked Nelson. "Overeem does really good at what he does. He's a good striker. Ground? Maybe not so much. Talk about dos Santos here, all he does is knock people out."

Nelson can crow loudly about JDS because he went 15 minutes with the champ and couldn't be finished.

On the topic of Lesnar, Nelson was pretty blunt during a discussion on his hometown radio station ESPN1100/98.9 FM in Las Vegas.

LAS VEGAS -- Nick Diaz is saying, but he's not saying.

The UFC interim welterweight title challenger showed up for his first round of media duties yesterday in Las Vegas. Our videographer Silton Buendia did a beautiful of piecing together what he could.

On the topic of being the favorite in his UFC 143 fight against Carlos Condit:

"We have a really even sort of record. One of us might ha fought harder opponents. I can't say that I have. I just figure that one of us, with all those fights, one of us has had harder opponents in there," Diaz told the media at UFC 143 workout day. "I know that everybody I've fought has been really, they've been really tough. I've never been fed any squids."

So Condit's resume is less impressive, right? That's exactly what Diaz said, or did he?

On the subject of Georges St-Pierre's ACL injury, Diaz has his doubts yet he doesn't.

LAS VEGAS -- Mike Pierce is a pretty reserved dude, but you can feel a quiet confidence coming from the welterweight prospect this week before UFC 143.

Pierce is trying to become the second straight fighter to knock off one the division's traditional gatekeepers. Between Koscheck (16-5, 14-5 UFC) and his teammate Jon Fitch (lost to Johny Hendricks), it's been pretty tough to crack the top three behind champion Georges St-Pierre.

"For a long time, those guys have been at the top. . they've had their chances fighting for the title ..josh kos jsut recently again fought Gsp for the title," Pierce told Cagewriter. "And I think this is a great opportunity for me to take advantage of an opportunity and get a win and move myself up."

Pierce didn't say much on "Countdown to UFC 143," but it definitely made an impression on Josh Koscheck. The veteran was irked by the fact that Pierce said Koscheck's striking game was predictable and that he wouldn't be able to use his heavy right-handed attack to score a knockout. Pierce says the fighters of today are versatile and unpredictable.

LAS VEGAS -- The crowds, money, adulation, safety precautions are all dynamite for 23-year-old Alex Cacares as he fights for the biggest mixed martial arts promotion in the world, but the Miami native misses the days of what appears to be a much more barbaric mode of fighting - the backyard brawl.

Those types of fights have been going down since the beginning of time. They recently became headliners again with the growth of YouTube and exposure for guys like Kimbo Slice in the Miami area.

As a hulking stack of muscle and intimidation, Slice fit the part. Cacares is slender and appears to be non-threatening, but when you hear him talk about his teenage experience with those pit fights you realize the kid loves to fight anywhere, anytime.

"I got into it because I was underage to get into professional fighting, "Cacares told Cagewriter just a few days before his 11 pro fight at UFC 143. "I was doing amateur fights at the time. I really wanted to get into a professional fighting, minimize the hand protection, no shin guards and really see what I could do."

The UFC currently uses four ounce gloves which are tiny compared to boxing's eight and 10 ounce models. Cacares still prefers the more primitive style of using bare-knuckles.

You got the wrong Dana White, says the real Dana White and a poor woman on the eastside of Las Vegas. The UFC president's battle with online hackers resulted in Julie Breeler getting hundreds of phone calls the last few days.

FOX5 Las Vegas covered the story of the woman getting harassed by haters of Dana White and even those calling him for a job. There is no Dana White at the address and it certainly isn't the home of the fight-promoting millionaire.

The UFC boss heard about the woman's plight and actually showed up at her house on Monday.

"[I] went over and apologized for all the trouble caused by the online terrorists," White told FOX5's Claudine Grant.

Breeler wasn't exactly greeting folks at her front door with open arms.

"Stone Cold" with Tyson in 1998 (AP)"The Baddest Man on the Planet" never donned wrestling tights, but Mike Tyson made an impact during several appearances for the WWE.
