I think he's suggesting that she still has periods where she doesn't play as hard as he feels she should or gets too nonchalant at things that need to be done. It might be a little bit of what Tina Charles did through a lot of her freshman and sophomore year before she really became the monster All American that she did in her junior and senior year.
I don't think the comparison to Tina is apt.
In her case, she was too nice, not aggressive, didn't comprehend the hights to which her talent could take her. Geno used every arrow in his quiver: sarcasm, disgust, outright humiliation and more to beat the message into her. And eventually, the light-bulb went on and she became the relentless campaigner that she has now become.
Stewie understands very well what she brings to the game, but at least this season displays it selectively.
There's a little war going on now between the two, one the I expect Geno will prevail in.
There's a 40 or 50 point game in our future with 8 blocks and 14 rebounds, mark my words.
