While playing for the Panthers he only lost one game while winning thirty decisions. He was a member of three national championship-winning teams under head coach Glenn "Pop" Warner. In 1916, the Panthers beat several national powers while not giving up a single point. During the next two seasons McLaren won All-America honors.
