let's see if the athelet in this kind sport can use drug

When Patrick Kane scored the winning goal, referes didn't even know what happened. His mind and body had to be in perfect condition to accomplish this. not even mention there are goalie and defends. see how fast this sport is and how quick they need to make decision and execute it, because the opportunity was just a split second.

Most HS kids in sport team don't use drugs. even if they use, only soft drugs and off the season. My son's school sent a kid to Duke as a starter in basketball team(NCAA champion this year).
