I agree with you to a point, but I certainly do not "suck" at drafting. I think that if you draft the proven guys, then you are all but guaranteed a consistent, competitive team (barring injuries). But if you put McGahee in your top 3, like you said, that means you are liable to use a top 5 pick on him, which I am not quite ready to do. I agree that the ingredients are there to make McGahee a star, but I would take a proven player in that spot, because if you do not, you could ruin your year (although I agree that McGahee will not be a bust by any means next year). I would tend to save these risks for the middle and latter parts of the draft, where a mistake would not kill you. Keep in mind that NBA Drafts are often ruined when they draft these high school players with "unlimited potential" instead of proven college stars. Yes, a select few go on to greatness (Kobe, Garnett, J. O'neal, etc), but there are many more who never even see the NBA court.
That being said, good luck in the upcoming year

. I hope McGahee pans out (I think he will, but not to the caliber of a top 3 RB). Maybe we can get into a league together and let our opposing strategies duke it out.
