Penn State tragedy: Barry Switzer says Joe Paterno had to go - Article Photos 2/7

In this file photo taken Oct. 22, 2011, Penn State coach Joe Paterno walks off the field after warmups before Penn State's NCAA college football game against Northwestern in Evanston, Ill. Penn State administrators canceled Paterno's weekly news conference Tuesday Nov. 8, 2011 in which he was expected to field questions about a sex abuse scandal involving a former assistant coach. Paterno's son Scott tells The Associated Press that the decision was made by president Graham Spanier's office. (AP Photo/Jim Prisching, File)
