I don't think we can just pass on top 10 talent. For one thing, we don't know how long Purvis and Hamilton will be here. One or both could blow up next year and be gone. For another, we don't know enough about how they all play. Hamilton seems like a willing passer (7 apg in high school, even if its padded) - Purvis and Dorsey could share the ball well in our system too. All of our Final Four teams have split point guard duties or had a score-first guy with the ball in his hands a lot. You just need guys who can make plays. Throw all three of them out there, exploit the weakest perimeter defender, and rotate the ball when the defense breaks down. You'll get open looks or good driving lanes.
And finally, I don't want to pass on Dorsey and have him end up kicking our ass in the tourney. One thing if we don't get him - another if he was interested in coming and we decided we didn't have room.
