It was and wasn't the Phillies fans. This is what the radio and TV announcers, chosen by the team, drummed into fans. The Phillies' official philosophy was that a 'star' who took a walk with a man in scoring position was a coward, who had chosen to shirk is responsibility, take the walk, and leave it to the next, lesser, hitter to drive in the run. The was the organizational philosophy in hte minor leagues. The coaches and managers were extremely critical of Michael Bourn for not being an RBI guy, which he wasn't built to be, rather than an OBP machine which fitted his abilities. The Phillies did their best to ruin him. He was the best OF the Phillies produced in recent years, although Houston got the benefit. I remember the write-ups when the Phillies drafted Dugan. Gillick overflowed with his enthusiasm for Dugan's nice swing, which kept his bat in the zone for an extra-long time. Although he was derailed by injuries, the development staff could not make him the best OBP hitter he could be, he had to be more of an upper cut hitter to generate more power. Just another case of drafting a guy for what he does really well and then trying to turn him into something else, entirely.
Abreu managed to be the best of both worlds: OBP and speed with above-average power. Even that wasn't good enough.
Ironically, when the Phillies have a plus power hitter, the team (through announcers), fans, and media moan about the large number of Ks and swear nobody (or team) with that many Ks can be good.
