Williams started at right tackle for the Tigers last season. Pierschbacker, one of the top prep lineman in the country, held down the left tackle spot.
"He had a big effect on me as a player and a person," William said. "I talked to him quite a bit and got advice. He just told me to play 100 percent all of the time and he helped me a lot with technique."
Williams now is the right guard for Cedar Falls. The Class of 2016 prospect is hoping to follow in Pierschbacher's footsteps and become a Division I college player.
"The recruiting was pretty easy for him," Williams said with a laugh. "He had everybody in the country after him. It's been a little harder for me to get attention."
"It was a fun trip. I talked with the O-Line Coach (Adam Cushing). He told me to come back whenever I wanted to. I could really tell the whole coaching staff cared a lot about the players and their futures. It's a lot about life and academics and then athletics. I liked that. The energy on the sideline also was great. They play loose," Williams said.
"I feel like I have good footwork and am good with my hands. I'm not afraid to put a kid down and I play smart," Williams said.
Williams was selected as a captain for Cedar Falls this year.
"I'm trying to contact as many colleges as I can," he said. "I fill out a lot of questionnaires and update my Hudl highlights every week and email, Tweet and Facebook those out."
