Oppose Avoid readers at Isiah Thomas (disambiguation) having to do a double take on a Isaiah Thomas (basketball) entry when the primary topic, Isiah Thomas, is also a basketball player.  "Isn't this the same as the primary topic?  Why is it listed twice. Ohhhh, there's an extra 'a' on this one.  Sigh."  AFAIK, this is the convention when the primary topic and a non-primary topic are in the same domain.  See Jordan Adams, male basketball player, and Jordan Adams (basketball, born 1981), female basketball player.—
