That's kind of funny but I can't imagine that she really thinks this. Geno is 991-135 - .880 winning %. Kim is at 506-96 - .841%.
The fastest coach to reach 600 wins is
Nancy Fahey, current head coach of the
Illinois Fighting Illini, who reached the mark in her 706th game as coach of the
Division III Washington (MO) Bears. Nancy was 600-106. Kim would have to go 94-10 over the next 3 years or so - certainly possible, but not likely as I would expect 3-4 losses each year plus another one in the NCAA's.
I don't think any coach will come close to Geno's all time winning %. Kim, for example, would need to go 485-39 over the next 14 years averaging less than 3 losses per year during that time frame. Highly unlikely...
