I can remember two freshmen who were never in Geno's doghouse (to my knowledge): Kelly Faris and Stef Dolson. Geno predicted before the first game that Kelly would never have a bad game at UConn (because the hustle and intelligence were always there even when her shot wasn't falling). She did have at least one bad game, against Duke in her freshman year, and although she was pulled from that game, she never got in Geno's doghouse.
If you recall, around January of Stef's freshman year, Geno said with some amazement that "Stef gets better by the week!"
