I didn't say Christian was better than Denham, and I said that Christian would not play in the NBA -- but that I wished he had a handle and better court vision, because if he could dribble and create for others then he would have a chance to play in the NBA.
As for Rashad's senior year, he had 15% of the team's points taking 17% of the shots. The only reason he got so many shots and points is that the team had a terrible dearth of guards -- Marcus Williams, Denham Brown, and Rashad, then a freshman Craig Austrie. The 5 players who played in the NBA were Marcus and four frontcourt players (Rudy Gay, Josh Boone, Hilton Armstrong, and Jeff Adrien). The bottom line is that team had NBA players at every position except Rashad's, and no outside shooters except Rashad. And the lack of a backup point guard or any real guard skills apart from shooting at the off guard is what killed that team against George Mason.
