Agreed. I didn't like any of those fights either, also because I want boxers to stay in boxing as I'm not much of a MMA fan. But: 1. One important difference is that boxing stars have a far better chance in the Octagon than MMA guys in the ring. The boxing talent pool is far larger, guys like Floyd or Pac are far more talented than the MMA guys. 2. None of those crossover fights were as high profile as Floyd-McGregor.
