I remember like it was just yesterday, Cain came into the UFC 2-0 and he was unknown by many. Dude came in and impressed the hell outta Goldie & Rogan, touting him as possibly the next best thing. JDS who was relatively unknown & new to the UFC was suppose to be a sacrificial lamb to Fabricio Werdum who was well on his way to a title shot if he won this fight & JDS came in to upset him w/ one of the most vicious uppercuts ever. Cain started blitzing through his opponents, fast tracking him to a title shot. Before we knew it, he destroyed Kongo followed by total domination of Ben Rothwell & his last test before his title shot. His big KO win over Big Nog. JDS took a longer path to the title, decimating a who's who in the division, from destroying Werdum in his debut, destroyng Yvel, Gonzaga, Struve & the legendary Cro Cop before crossing paths w/ Nelson whom was his first decision win in the UFC followed by his last obstacle in the dangerously powerful Shane Carwin whom he dominated. JDS blitzed through his opponents as fast as Cain did, Cain reached the top in where everybody claimed that the biggest dude will be the hardest to dethrone. Cain proved everybody wrong & JDS did as well, that the biggest guys in the weight class wouldn't be a dominating factor in the HW division. November 21st, 2011 came & these beasts fought for the title in what I believed should've been a war but JDS came out the victor with a HL KO reel & left Cain down at that #2 spot, but this ignited a flame in Cain. UFC 146 came along earlier this year, revenge was on Cain's mind and he solidified that w/ hands down the bloodiest contested beatdown we've seen in quite sometime. JDS also fought on that card & proved Mir had no business trying to be at the top heap of the division. He made Mir look like he didn't belong in the cage w/ him and eventually Mir gave up and JDS just TKO'd him into the bottom of the Top 10. These two fight tonight for a 2nd time for the HW championship and only one will leave the victor. Regardless of what happens tonight, everybody has to admit that watching these two tag team the whole HW division was one of the most interesting things to happen to the division in quite some time. It's crazy that both are the #1 & #2 HW's in the world & I'm glad I watched them from back then til' now.
