In re the JWill and Acuff discussion in this thread - not sure why it is here, but, whatever:
Versus Illinois those arguing JWill's 1st half was poor defensively need to understand what his role WAS defensively: First and foremost it was to limit Jakucionis. Which he did very well. And also forced Jakucionis to the bench with 2 fouls.
In the 2nd half, Williams again started off against Jakucionis - and continued top do well defensively. When Davis was in the game and Jakucionis was also in, Davis covered Jakucionis - otherwise it was Williams.
Then, in the 2nd half when Riley got going, for the last 10-12 minutes, Pikiell put in both Williams and Davis, and had Davis cover Jakucionis and Williams cover Riley.
Williams was excellent on Riley in that stretch, picking his pocket once, and with Sommerville helping on a drive forced Riley into a travel, and forcing a number of missed shots. In fact, Williams entered the game at the 10:28 mark, RU down 52-53, Illinois scored to go up 52-55 at the 10:06 mark. From there, Riley hit a 3-pointer at the 8:34 mark to let Illinois take a 58-60 lead - and was scoreless for the next 8+ minutes: 0-5 FG, 2 turnovers ... all with Williams defending him. Just saying ...
