Henderson plays the 2 guard. Lawson is a PG, and Hansbrough is a PF. You can't really compare their draft positions because they play different positions. You can compare players of similar positions and who is drafted where is based on a number of things. Perceived potential, system, etc. will all play a role in who gets drafted where.
Where someone is drafted is going to tell us who the better player in college was? Is Henderson better than Hansbrough and Lawson? I am not buying what you are selling I could care less where someone is drafted while I am watching college basketball, it doesn't tell me who the best player was.
Besides I'm done with this conversation. It has nothing to do with anything. I still believe Carolina has the advantage in the post, while UK has the advantage on the perimeter. You believe what you want and I'll believe what I want.
