Yes even if its a 2% chance, there always that risk.
Lets go at it from a different angle. My dad works 40 hours/week. It takes him nearly 40 minutes to get to work one way. Do you know what my dad's boss would say if he said he was too tired to come into work today? He would probably be out looking for another job. Believe it or not, nba players have a job to do and they get paid a handsome sum of money to work roughly 12 hours a week. Their day consists of lounging around in the lockeroom all day listening to tunes while they stretch, playing video games and watching TV which takes them right up until game time. Then its go time for 2 and a half hours. Are you telling me for 10 million dollars, you can't give the team a solid 10 to 12 hours a week? , I work out for nearly 2 hours a day without days off. I must be some sort of super hero.
