I will admit that the media guide for this season was my jumping off point, having minimal experience with the conference prior to this season outside of whatever national blips and blurbs existed about Mitchell.
That said, with a full on reading, cover to cover, of that media guide, I created a list of players that I think is fair and accurate outside of your contention of Mitchell as a clear-cut #1. You are absolutely correct that, at this point in time, Mitchell has a much higher ceiling than Rubit. But I'm not writing a top ten list based on how good these players could be, I'm writing it based on how they have produced thusfar.
Mitchell is superior to Rubit in terms of potential NBA talent, but Rubit - partly due to two years of production (he was Frosh of the Year right before Mitchell, remember) is only a shade behind Mitchell in terms of ability right now.
I'm assuming it's the distribution and not the sequence you are at odds with, and I will admit I initially had it as a clear 1-2, but later changed my mind. Feel free to hop on over there and comment, and also keep an eye out later this week for an interview with USA coach Ron Arrow about the upcoming season.
