Brock Lesnar vs Randy "the natural"?

All i want to know is how in the hell did brock lesnar earn himself a tittle shot against randy. Is it that fighters no longer have to have a good fight record to even be considered to fight for the belt!. Just look at Randy's accomplishments and not just that but the amount of fights and dedication,sacrifice that he has given to the sport. I just think its flat out ridiculous that lesnar would have the right to step into the ring with somebody of Randy's stature. I know its all money driven but its just pathetic that lesnar has not proven nor has fought nearly half as many fights as the natural! People don't see that, there are tons of other great fighters who are 12-0 or 9-0 and aren't even close to a tittle match and here's lesnar who is a joke,who's lost half of his fights(4) i'm tired of this crap because fighters like diego sanchez who have proven to be contenders always have one more fight to prove, is the UFC going to wait until they are 46-1 to give them a tittle shot!
