Arthur LeMarcus Banks (no Marcus isn't his actual name, he just went by it; why didn't he go by "LeMarcus" if that was his middle name?) attended Cimarron HS in Las Vegas before beginning at Dixie College, a junior college, in St. George, Utah. After two years there (he's in the Dixie College Hall of Fame) he went onto UNLV.
In June of 2003 it was Danny Ainge's first draft as Celtics' general manager and as you can see from the above quote, was thrilled the Celtics were able to land him.
Marcus Banks was lightning quick.
