Sean Williams is a defensive force at power forward at that’s exactly what the doctor ordered for the Nets.  Williams has nice size at 6′10″, 235 pounds and he should develop into a good rebounder.  He played in 69 games at Boston College and he averaged 5.5 points, 4.2 rebounds and 2.8 blocked shots per game.  Most of his shots are from very close range as he hit 57.7% shots from the floor but only 60.5% on his free throws.  Look for him to be a starter from Day #1 unless the Nets re-sign Mikki Moore.
