Ok guys, this is my interpretation of Geno's comments ....
There is always a player on the team who earns Geno's needles about being the worst defender in the world, not being able to guard the chair they are sitting on, etc. In the case of Dolson, he put a piece of paper on the floor and commented that he was amazed that she had just got airborne enough to clear that obstacle.
The first player that earned that 'honor' that I am aware of was Rebecca Lobo, but by the time she was a senior the honor had been passed to Kara Wolters. And it has been passed down as a badge of honor from one NPOY, to another first team AA to another NPOY to the holder of the title the last few year Miss Stewart. Are you beginning to see a picture emerging? It truly is a badge of honor, because it only gets 'worn' by those players who have the potential to become great. It is his way of keeping them sharp and pee'd off with him, and determined to shut him up.
After the DePaul game we got the first inkling of the next title holder Miss Samuelson, and after the ND game it was pretty well confirmed.
The interesting thing is there are a second group of players who seemingly can do no wrong - it is a rarer breed, and the first I remember was Nykesha Sales, who earned the epithet 'Precious' from her teammates because she NEVER got yelled at by Geno. Other holders of that title that I am aware of are Kelly Faris and Morgan Tuck. It isn't necessarily that they are better than say the 'worst defenders in the world' players, but they are extremely competent and do not seem to need or maybe do not respond well to Geno's needling.
I suspect Miss Collier may fall into this category during her career, but it is harder to really detect, because you are looking for signs of an absence of comment as opposed to the presence of the needling comments.
