UFC 137: Where Does Nick Diaz Rank Among GSP's Toughest Opponents?

0 of 5

    Nick Diaz beat BJ Penn at UFC 137, and his next fight will be against Georges St.Pierre. GSP has fought and beat the who's who of the division for a long time, and Diaz is one guy he hasn't squared off against. It will for sure make for an entertaining fight, as both guys could walk home with the belt.

    St.Pierre has turned in many dominant performances, and he will look to do the same against Nick Diaz. Diaz will be one of the toughest guys that GSP has fought up till now.

5. Josh Koscheck

1 of 5

    Josh Koscheck is a solid mixed martial artist who has been able to develop his game very well. Koscheck is a good wrestler with a big right hand. 

    He was a big challenge going into the second fight with GSP, but the champ prevailed with improved boxing and his always solid wrestling.

4. Jon Fitch

2 of 5

    Jon Fitch is vastly underrated, and is one of the best fighters in any division. He routinely dominates opponents in the same fashion every time.

    There's no secret to what Fitch is going to do in a fight, but guys just can't crack his style. Fitch has adapted his wrestling ability to MMA extremely well.

    He put up a good fight against GSP, but still didn't have the ability to beat the long-time champion.

3. BJ Penn

3 of 5

    BJ Penn would be much higher on this list, but his size at the time was a big disadvantage. I think for Penn to have a better chance, he would have needed a fight or two at welterweight to bulk up.

    Regardless, Penn was a very tough fight for GSP. Penn is a UFC great, and is one of the best mixed martial artists ever.

2. Nick Diaz

4 of 5

    Nick Diaz presents a very big threat to GSP, and will be the second toughest matchup of his career. Diaz's boxing, cardio and tremendous ground game is what puts him on this level.

    Diaz is relentless, and will offer a very unique advantage over GSP. He will have to train hard for this fight, as it could be the bout that ends his tremendous title run.

1. Matt Hughes

5 of 5

    In his prime, Matt Hughes was a beast. He was one of the best welterweight champions of all time.

    In their first fight, Hughes was able to humble GSP, and beat him with an armbar. 

    Matt Hughes is a tremendous wrestler, and one of the best functional wrestlers of all time. In his prime, he was the toughest fighter that GSP has faced.
