PHILADELPHIA- From their freshman year to today, the Temple linebacker corps have had a complete transformation. When the now upperclassmen first arrived on campus, the linebacker group lacked collegiate experience and depth. Some guys had transitioned from other positions to play linebacker, and others had gotten injured along the way. Now, just four seasons later, the Owls' linebackers are the most seasoned veterans on defense and are one of the fiercest groups in the American Athletic Conference, if not all of college football. Chapelle Russell, Shaun Bradley, Isaiah Graham-Mobley, William Kwenkeu, and Sam Franklin have come a long way over four seasons and are playing their best football heading into spring practices.
