If Diego didn’t become a rockem sockem striker, he wouldn’t have lasted in the UFC. He isn’t a contender and his record isn’t that great. A grappler in his position would get cut for being boring. Grapplers with far better records have been cut. By reinventing himself into an “exciting“ fan favorite, however, he carved out that narrow niche that exists for strikers who aren’t ever going to sniff a title, but will always put on a show. That’s one way to keep your job in the UFC.
