To his fellow Giants catchers, Buster Posey's Major League skills have an Ivy League quality to them. Whether it's by example or with occasional words of wisdom, Posey furthers the continuing education of San Francisco's receivers. Posey's curriculum vitae includes the National League Rookie of the Year and Most Valuable Player awards, three NL All-Star team selections and two NL Silver Slugger trophies. That lends weight to Posey's words and deeds, as if he were a tenured professor.
