Josh Smith’s eligibility isn’t the only surprise roster addition this week on the Hilltop.

Riyan Williams, a 6-foot-4 sophomore guard and son of famed Hoya Reggie Williams, has made the team as a walk-on and should make his debut at tonight’s Tip Off ceremony.

Williams played in the Nike Pro-City League (commonly known as the Kenner League) this summer and played alongside several Hoyas on the Clyde’s squad. However, his status for the year wasn’t confirmed until Tuesday, when Head Coach John Thompson III indicated that he was indeed on the team.

We don’t know much about Williams yet, but Casual Hoya’s reports from the Kenner League indicate that he’s a versatile scorer with range past the three-point line.

The Kenner League isn’t the Big East by any means, and fans won’t expect a walk-on to seriously contribute. But Casual’s reports have to be encouraging for Hoya fans nonetheless — adding depth to an already talented backcourt without expending a scholarship is an all-around win.

And besides, remember what happened last time a Williams made his Georgetown debut?
