Curious about how the BJJ skills of Roger Gracie, Jacare and Demian Maia compare. Reason I ask is when Maia first came to the UFC, he went on a tear, particularly because of his BJJ. But as he went up the ranks, this became less and less of an advantage (see Silva, Marquardt). He eventually had to become more well rounded. His striking eventually improved and didn't look bad against Munoz (despite the loss). So let's assume Jacare and Roger have the same learning curve. The first 2-3 fights they can showcase their superior BJJ, but eventually they may encounter a fighter who can nullify these skills unless their BJJ skills are so good that they can continue to use these skills right to the top 5 or 3. So those in the know (as I am not), how do the BJJ skills of Maia, Roger and Jacare compare to each other (as Maia has held the title IMO of having his BJJ skills hyped the most by he UFC), and on top of that, do you think Jacare and Roger can develop their striking in the same path that Maia has where is can be a decent tool, if not improved? Thanks in advance.
