A series of freak accidents derailed a season that began with seemingly realistic national championship hopes. Oklahoma lost five games for the first time since Coach Bob Stoops' first season in 1999. Now, the Sooners hope to do exactly what the 2000 team did: build a five-loss team into a national champion. That's not an outlandish proposition, especially if the Sooners can stay healthy on offense. Between Jones, Broyles, tailback DeMarco Murray and a line that includes eight players who started at least one game last season, Oklahoma has the raw material to put up numbers similar to the ones it amassed in 2008, when Bradford won the Heisman and the Big 12 champion Sooners played for the BCS title.
