Geno is a perfectionist and sees all the weaknesses. They keep him up at night. Every year we have weaknesses. Some are major, and some are minor. He tries to shore them up or hide them. He is driven by his perfectionism and experiences from his youth when he tried to prove himself and be accepted.
Yes, he is hard on the players who want to be driven. At one point, CD asked Tina if she still wanted to be an AA. She told Tina that Geno would ease up if she had lowered her goals. Tina, of course, said that she wanted to be an AA. She's now on the short list of best players in the world.
Geno generally is toughest on the best players, because he doesn't want to let them cheat their talent. He was tough on Diana, Tina, Maya, Stewie, et al. OTOH, he rarely criticized Nykesha or Morgan. Maya was a special case, because she always played hard and was unbelievably talented. She was stubborn and sometimes wanted to do things her way, but Geno never faulted her for lack of effort.
Geno expects all the kids to play hard, whether its the HS POY Lou or the former walk-on Tierney. He doesn't expect the same level of play, but he does expect the same level of effort.
With regard to Pheesa, yes she is Silky! She glides and almost always does something positive. The comment about helping everyone out reminded me of his comment on Bria about 3-4 years ago: She guarded both baskets (played good defense and shot something like 1-14).
