Sure, there are a lot of switch-hitters. Guys like Hagler or Loma who switch back-and-forth seamlessly during combinations without thinking. I'm wondering if you guys know any boxers whose switch to orthodox (or southpaw) presents an entirely different style. I mention Crawford because it seems like his entire 'fighting personality' shifts when he changes stance. Setting completely different psychological rules for engaging with their opponent.
Goerge from that movie Blow. He was good at switching. From Bad-Good guy to bad-bad guy. High I.Q. Protect yourself at all times. Kill or be killed.
