As a teenager, Pau Gasol expected to be a doctor.  It wasn't until he was 17 that there was any hint he might be a serious basketball player.  "At 16, he was very skinny," said Arturo Ortega, Gasol's Barcelona agent. "He could not push anybody around. No one knew how talented he was until eight or nine months ago." Now, he can hardly walk the streets of his native Spain without incident.  The Memphis Commercial Appeal has two articles introducing their latest hope to his new fans.  Any comparisons?  Well, ummm, one to Kevin Garnett and one to a "Michael Jordan-esque leader of F.C. Barcelona."
