"EFRAM" for EFREN
Regarding Efren frequently mispronounced as Efram by more than a few pro players (Hopkins, Sigel, Varner, etc) here IMO is the precise reason (however inexcusable, to some) for it: For many Americans and Canadians -- equally intelligent as you and I -- in that time period (and even now) it was more reflexive to see, hear, and pronounce, the word "Efren" as Ephrem because of the multi-season, hugely popular FBI TV series starring the oddly-named Ephram Zimbalist. In any country, sound-alike prenoms and even surnames are routinely and erroneously conflated even by highly literate folks. Can happen with any language.
The "Efram" thing as mispronounced by certain respected pros -- on mic -- and more importantly in years of casual general conversation between players, had spread contagiously to all levels of players in many regions of the country. I heard it in a number of states where sweators were watching or awaiting some of Efren's matches whether tournament ones or gambling ones. I sometimes felt that it was occasionally a xenophobic, "other-izing" conscious thing, and alternately seemed a cute "moniker-ing", actually diminishing thing to engage in by those on the losing end of a bet. Who knows or cares anymore.
