I remember in the late 70's very few Whites played the outfield and the few that did were basically journeymen or fading veterans. Aside from Richie Zisk and Fred Lynn I can't recall an other star outfielder from that time period in the AL, there were some star middle infielders like Patek and Belanger. The NL because of the no dh rule forced teams to play less agile guys who could hit for power but were defensively poor like Luzinski and Kingman.
Ps Guys like Palmeiro and Gonzo are considered White in Cuba, it's only America where ethnic pandering for minority status forces people like this to associate themselves with an "oppressed" minority group.
That's true, for a while there outfielders became overwhelmingly black. Blacks had a short glory period in baseball lasting from the 1960s through the '70s but mostly the '60s. Ever since then it's been wailing and whining by the usual suspects that there's not enough of them. Clearly blacks "just aren't interested" in earning $20 million a year for 15 years or MLB would look just like the NFL and NBA. There's no other possible explanation. [sarcasm]
