"He and my brother were a couple of years apart," Shaw said of Angerer. "I saw him wrestle and play football. You have to be a fan of him.
"He's actually come back during the summer a few times. I got to talk to him quite a bit. He texts me once in a while to ask how recruiting is going. He's a pretty cool guy."
Iowa has been recruiting Shaw, although the Hawkeyes haven't extended a scholarship offer. Assistant Reese Morgan visited his home last week.
"He got to know my family a little bit better," Shaw said. "We talked about different things about recruiting. He said that maybe next time we talk he'll hopefully have an offer for me. He said they're really slow at giving out offers."
"The reason I'm waiting to commit is I just feel like there are more offers are going to come in," Shaw said. "I just don't want to rule out anyone before that happens. I'm just keeping my options open."
Shaw said he will officially visit Northern Iowa this weekend and Southern Illinois the following week.
"I think I put together the best resume I can," the 6-foot-1, 210-pound Shaw said. "We did a lot of great things as a team. I broke Angerer's tackle record, which was amazing. I went to quite a few camps and I performed very well at those. I was pretty happy about that."
Shaw said that he's versatile enough to play inside or outside at linebacker. He prefers roving the middle, however.
"I think I fly to the ball very well," Shaw said. "I can read the ball, but when it comes to finding the holes and finding the ball, I'm very good at that. I'm a pretty good leader. I work really well with other people. If you're going to be on defense, you have to have that because you're almost as a family. You have to play the best you can with them."
Shaw, who grew up an Iowa fan, also has made a name for himself on the mat. He's posted a 18-1 wrestling record this season with his only loss coming last weekend in the finals of a national tournament in Wisconsin.
While there's a degree of unknown with his Iowa relationship, Shaw is encouraged by his relations with the Hawkeyes.
"I feel like I'm up there on their board," he said. "I'm not exactly sure what they're thinking. I know I'm up there and I think I'm on their radar."
