I think the UK ranking at #1 is pretty speculative at this point when you've got other teams with established players. I would have them down around us (in the #5-8 range). Poythress and Marcus Lee may turn out to be great players, but nothing we've really seen over the past couple seasons would really support that they're anything more than great natural athletes. Also, unless they make another couple major additions, they don't really have any bigtime wing scorers (it looks as if they intend to start Poythress and Briscoe -- a PG prospect who doesn't shoot the ball particularly well) or really many guys who you'd give the ball to and say make a play. Ullis can do some of that, but it's going to be a whole different world for him now that teams will be focusing their attention on keeping him out of the lane. While there's clearly talent on this roster, I'm not sure how well it all fits together or whether they have the shooting / playmaking to have any consistency at that end of the court. It looks to me that they'll have a very good defensive team that you won't want to face on nights they're hot, but which will have a tough time scoring on a lot of nights -- i.e., maybe a slightly better version of Louisville this season.
