Be careful on this one guys . Brock is very athletic and learning the game quickly . Randy should win this one . I would think by submission . But he won't be boxing him and dominating the tie up as he likes to do with Brock.....I would be impressed if Randy at 46, can get by someone as physical as Lesner . [I hope he does ] If Randy wins ,then he has to beat Nog , who will be very hard for him to beat[would be even more amazed if Randy can beat him ] . Then and only then ,can he be deserving of Fedor. I really hope Randy can pull the shocker and win those three fights and retire a legend . My take is he in trouble and may have struggle against Lesner . Being that Brock is bigger ,stronger , faster , more explosive , and can wrestle . That is a tuff task for a guy like Randy that likes to dirty box and ground and pound . No way he gets that chance against Brock........he is going to press him and try to put Randy on his back .......Randy has a chance to via sub ......but that isn't his game at all ....my hats off to Randy if he can win this fight
