The 6-foot-4, 215-pound defensive end was also being recruited by Iowa but had no other current offers. Devin said Iowa State has been looking at him for a while.
"They started recruiting me last year and then Coach Burnham invited me up for their camp a few weeks ago," said Lemke. "A few days later they told me that I had really impressed them at the camp with my speed and ability to get to the quarterback. Then Coach Rhoads told me that they were offering me a scholarship."
Devin said that he is also very excited to be staying close to home.
"It means a lot to know that I'll be representing my home state," said Lemke. "My family is proud of me and my decision to pick Iowa State really made them happy and everyone is just really excited."
Devin added that he'll be playing for the team that he has always favored.
"I've always liked Iowa State and I never really liked Iowa so it feels really good," he said. "I'm just very impressed with how Coach Rhoads got the program turned around last year with them going and winning the Insight Bowl."
Devin also has one more thing he needs to do before he can officially become an Iowa State Cyclone.
"My grades are fine but I just have to bring up my ACT score a little bit," he said. "The next time I'll be taking it is September 11th and I'm really confident that I can move my score up to make sure I qualify."
