The UFC on Fox 2 this Saturday night is the biggest card of the year because it will decide whether the UFC will have two grudge matches that fans have been anxiously anticipating.

When the cage door closes behind Rashad Evans and Chael Sonnen, both fighters will have one obstacle in the way of getting at their rivals.

All Evans has to do is get past Phil Davis to fulfill his destiny and fight the greatest light heavyweight the UFC has ever seen: Jon Jones. As for Sonnen, he gets a chance to take on Anderson Silva for one of the biggest rematches in UFC history, should he defeat Michael Bisping.

Both fighters will have their hands full with these opponents. Evans is facing a young up-and-comer who just might possess the wrestling skills to take Evans’ No. 1 title.

Evans’ wrestling skills in his mind are second to none, but Davis is a four-time NCAA Division I All-American Wrestler and 2008 NCAA Division I Wrestling Champion.

If Evans can keep the fight standing, he should have a distinct advantage in striking. He has shown some lethal strikes during victories over Sean Salmon and Chuck Liddell.

Should Evans get past Davis, the title fight with Jones will be the biggest grudge match for the light heavyweight championship since Chuck Liddell fought Tito Ortiz at UFC 66. The fighters hate each other, and the fact that both of them have trained together and know each other’s tendencies, makes for an exciting clash.

Evans has the best chance of dethroning Jones in a fight that could be one of the biggest of the year.

However, it would not be bigger than Sonnen vs. Silva II. If Sonnen gets past Bisping, the rematch between him and Silva will take place in a soccer stadium in Brazil.

Sonnen is the only fighter to ever really come close to beating Silva in the UFC, and Sonnen was less than three minutes away from winning a decisive victory against Silva. After Silva slipped on a triangle choke in the fifth round to reclaim his title at UFC 117, Sonnen has fought his way back to challenging for the title after beating Brian Stann at UFC 136 with an arm-triangle choke.

Silva’s victory over Sonnen was the craziest thing I have ever seen in sports and it is my favorite fight of all time, mostly because of the way Silva came back and how Sonnen was able to dominate a man that seemed untouchable in the UFC.

Sonnen talked a lot of trash before the fight and backed it all up and came just short of dethroning Silva. With Bisping, Sonnen needs to take him to the ground and work his ground-and-pound. I believe that that is just what Sonnen will do, and the rematch should be set after Saturday night.

The outcomes of the fights Saturday could make this the most exciting year in UFC history.
