When you design the shoes worn by the best (non-retired) basketball player on the planet, you have some juice. Jason Petrie has been the man behind Nike's LeBron line since the VII, and in a few short years has made quite the impact. It hasn't hurt that LeBron has won two MVPs since Petrie took over his line (and is likely to receive his third in a couple of weeks). Is he this generation's Tinker? Time will tell.
