What is the current word used to describe someone who's primary mission in life is obtaining his next sack and who lacks motivation to do anything meaningful in life? I was never a user but I've had plenty of friends who were and I know there are some very successful heavy users (Bill Walton, Cliff Robinson, Phil Jackson just to keep it in the scope of basketball) but I can say all of the ones I've known lacked career motivation and maturity. It's like their life stopped evolving in college and has stayed that way since then.
