I helped out with a free agent mini camp for the Oklahoma City Thunder in the summer of 2009. The players at this camp were all good players that were a step or an opportunity away from making it to the NBA. Checking into the hotel the day before camp I met former Kansas point guard, Aaron Miles. He was friendly and polite and instantly someone I liked.
As we started workouts the next day I ended up giving Aaron defensive pressure in a shooting drill. Instinctively I put my hand out and near his hip. He responded by slapping it away – HARD. The next time through my hand went up again and he again slapped it away – HARD. I have to admit that for a split second I was worried that I had offended him or was bothering him. Aaron got back in line, another coach stepped up to defend and stuck his hand out and Aaron slapped it away. I realized that for Aaron, it was just a reflex.
Even in a shooting drill these players practiced like they play. That is the only way you will make the next step in your development.
