Individual teams are not picked based on their individual NET, so I'm not worried about the 90 number right now. Especially since its fluid.
Teams are based on quality of their wins and losses -- which is why its important that your conference mates have good NET's. I'm not too worried about our NET being low right now. I'm more worried about our capability of winning 11+ ACC games, and the ACC staying steady or improving a bit in December.
The ACC is potentially just strong enough this year, could certainly be better though, that we can get that conference in quality play with the right breaks. Will need one signature top level win somewhere though. Doesn't need to be tomorrow, but will need to be Duke, Louisville or perhaps another ACC team that really rises in conference play to a top 15 national level.
