She might not have been completely done winning championships, but the sport was becoming more competitive and Geno really started to go on a roll in 2008 where his UConn teams were simply more dominant than Pat's (and everyone else's). I think it is likely that if Pat was still around and coaching with no health issues, Geno probably would have still passed her, but who knows.
Geno did not outdo Pat nor will he in the future. Ask the question Greatest Woman's College Basketball Coach and the first name that comes to mind is Coach Pat Head Summit and not anybody else. He is not in the same league with her and will always be 2nd or 3rd which is very unfortunate for you. Everybody knows CPHS and will list her over What's his name 9 out of 10 times.
