UFC 100's climactic finish on Saturday night will feature a rematch between former WWE superstar professional wrestler and current UFC Heavyweight champion Brock Lesnar and former UFC Heavyweight champion and current interim UFC Heavyweight champion Frank Mir. It promises to be a true clash of technique vs. strength. In their first match at UFC 81 in February of 2008, Lesnar had only one professional MMA bout under his belt, a win over Min-Soo Kim at K-1 Dynamite! USA in June of 2007. Lesnar's lack of experience was the main focus of Mir's gameplan in their first bout, and he subsequently submitted Lesnar via kneebar in the first round of the fight.

Today, things have completely changed. Mir went on to coach on The Ultimate Fighter Season 8 against PRIDE veteran Antonio Rodrigo Nogueira. The coaches' bout after the show gave Mir a shot at Nogueira's UFC Interim Heavyweight title (created due to Randy Couture's holdout from the UFC). Mir TKO'd Nogueira in the second round of the bout at UFC 92, winning the belt and convincing many that he was the true champion of the division.

Unfortunately for Mir, fortune smiled on Lesnar. After a dominating performance against Heath Herring at UFC 87, Lesnar was given the opportunity to fight a returning Randy Couture for the UFC Heavyweight title. On November 15th, 2008, Lesnar vs. Couture took place at UFC 91 with Lesnar defeating Couture via TKO in the second round after Lesnar landed a right that downed Couture. Couture worked a solid gameplan of using his Greco-Roman wrestling and clinch work to wear down Lesnar, but Couture later stated that Lesnar's reach was such a huge factor in the fight because it makes his punches almost impossible to avoid. The win set up the unification bout between Mir and Lesnar.

We're now back to the same question that was seemingly answered in the first bout between Mir and Lesnar. Does Brock Lesnar have the submission defense and experience to avoid Mir's strengths? Interestingly enough, UFC 87 saw some changes in Brock Lesnar's training regiment as he brought in seven-time BJJ world champion and ADCC veteran Rodrigo "Comprido" Medeiros to help him with his submission defense. Medeiros will also help add some submission skills to Lesnar's game, which could become a huge asset considering his overall strength.

With a couple of fights under his belt following his defeat at the hands of Frank Mir and the added trainers to help him improve his MMA skill set, can Brock Lesnar truly defeat a fighter who has been training BJJ for years and has suddenly gained a gas tank?

Mir has stated that his gameplan could revolve around Lesnar's immense size and conditioning. Lesnar's huge physique should suck in a lot more oxygen than your average heavyweight fighter, but he can also end a fight quickly with such huge power. It was evident in the Couture fight that Lesnar was beginning to tire toward the middle of the second round, but he quickly snuffed any hopes that the match could be won by Couture in the later rounds. Couture stated recently that Mir's plan is probably not the best idea considering Lesnar's reach, but Mir could also be driving home a skillful plan of misdirection using the media.

In the end, the bout comes down to whether Lesnar can avoid the submission. If Mir truly thinks he can strike with Lesnar, he's probably going to lose. Standing in a cage for five rounds with a man who has such immense power in his punches isn't good even if Lesnar's stand-up boxing isn't that great. He's eventually going to land a shot that is going to hurt enough to visibly show Lesnar that it's time to crush you.

Mir's best chance is to work the submission game, and to be perfectly honest, the heel hook, ankle lock, or kneebar is the perfect weapon once again. Lesnar's size doesn't exactly work to his advantage when it comes to leg attack submissions. Mir has stated over and over again in the media that bigger heavyweights are slower than him, so why not take full advantage of that by showing Lesnar some submission skills that he isn't expecting. I think it's the only chance he has of winning this fight.
