I've been hearing threats of fan boycotts since Ralph Nadar was threatening one (it might have been over the Seaver trade). The problem, of course, is that you'd need a large pct of fans going along and, as much as we don't want to admit it, some fans LOVE the DH, ghost runners, games decided by HR derbies (or maybe relay races), increased inter-league play, and little propellers on top of the players' caps.
