You can't teach this reactive competitive savagery, nor can you tame it. Athletes like Bryce Harper, Serena Williams, Sidney Crosby to name a few, are wired from birth to focus on winning at all costs and take no prisoners. If they make some friends on their journey to winning the universe, great, but that's not what they're here for.
Its not all fun and games with these athletes, and if you poke the bear, someone will get hurt.
Tip of the cap to both of these guys. Savages!
