SMU graduate assistant/RBs coach Timmy Chang visited with PonyFans.com to discuss how the Mustangs will replace Zach Line, the talents of Traylon Shead, how Prescott Line differs from his brother, how K.C. Nlemchi has developed ... and what it's like to coach RBs after a record-setting career as a quarterback.

(Not sure why the video came out so light/bright .... sorry — call it "technical difficulties.")
