Definitely Williams. He fits right in to our biggest need, and is probably the most NBA-ready player coming out because of his body and 4 years of experience.
Also, Roy for us would have been horrible. He's awesome, but he can't play the point any more than JJ. I would have loved Foye, but not Roy. Either way Shelden will do very well. I expect him to be in the top 3 candidates for R.O.Y.
Now the pressure is on BK to find us a real PG this summer
