I've had this sherdog account for about 5 years, and been browsing the forums since like 2008. I can't really remember a fight/rivalry that has divided sherdog as much as Conor vs. Khabib, can you? Perhaps it's just recency bias, but this feels like by far the #1 divider in Sherdog history that I've seen. Some other ones that come to mind: Sonnen vs. Silva 2 -My memory from this is foggy, but I remember this being a big one given the buildup, their 1st fight, Chael's promotion. GSP vs. BJ Penn 2 -One of the best build ups to a fight ever IMO (their 2nd one). There were some die-hard Penn fans that were devastated from this fight, understandably. Lesnar vs. Mir 2 -I think now that time has passed, people generally like Lesnar and what he has done in MMA (minus the USADA debacle) but I remember back when he was making a tear in the UFC HW division, people who were not a fan of his/the fact he came from the WWE were banking on Mir being the one to overthrow him.
