Commack sixth and seventh graders were motivated by Rohan Murphy to overcome any obstacle confronting them during an assembly Wednesday.
 
 The middle school wrestling team then was thrilled to receive pointers during practice from the former Penn State wrestler, who achieved great heights after a birth defect led to his legs being amputated at age 4.
 
 “The kids gravitate to him,” principal Michael Larson said. “From his speech and his experiences, they learn that they can overcome any obstacle they may be facing. The message definitely resonates.”
 
 Said Murphy: “I’m so appreciative that Commack brings me in each year to speak to the middle school students. This was my 10th year speaking here. I just thought it would be fun if I came down to wrestling practice and wrestled with some of the students for a little bit.”
