With his continued recruitment and coaching success, Williams has built Beaver’s men’s basketball program into a national competitor.

In 2008-2009 Williams led Beaver to a 24-7 record. Notable victories included wins over NCAA Division III schools Geneva College (Beaver Falls, PA) and Franciscan University (Steubenville, OH) for the first time in Beaver's history. The Lions went on to capture the PSUAC West Division Title as well as the PSUAC Conference Championship with an 86-70 win over Penn State Hazleton at the Bryce Jordan Center, Penn State University Park.

Beaver had another record year in 2009-2010. Williams led them to their second consecutive 20-win season and their first #1 USCAA top 20 ranking. The season was the second consecutive season that the Nittany Lions won the PSUAC Conference championship, 91-68, against Penn College (Williamsport, PA).

Individual awards came along as well during the championship season. Zach Fethin was named PSUAC Co-Player of the year and First-Team USCAA All American. Williams was named PSUAC Coach of the Year for the second time in two years.
