Frank Mir is not afraid of Brock Lesnar's heavy body or height. He is concerned about Lesnar's reach. Why would he think about Lesnar's reach? Everyone of us may think that Lesnar won because he is so big and he has a terrible heavy shot but that's not about it. His reach is actually long.

Frank Mir have watched the video of Lesnar's fight against Randy Couture. He saw that Rany was defeated because at the time Randy took a shot but it didn't reach Brock's face. Then, he slipped that punch from Brock and he thought Brock was out but the punches keep on coming that made him down.

Frank Mir is now practicing with taller sparring mate. Mir said that he is practicing with someone taller than Brock so that he can actually cope with the fight on Saturday.

Would it help him on Saturday? Let's see. But while he was practicing with taller sparring mate, Lesnar is practicing the defense.
